Next I drove back to the bridge I had passed under on my way to the one I just went over.  Okay, this bridge is completely insane.  Completely impossible.  I was disappointed, but I decided it was impossible; I was going to have to leave it.  But then I thought, well . . . let's at least look at it a little bit.
 
So, there is an intersection of two giant roads.  Four lanes plus left turn and right turn lanes in every direction, plus medians, so it is six lanes across plus the median in every direction.  The bridge goes from east to west on the north side of the intersection.  Normally a pedestrian bridge is far from any other intersection.  The entire point of the bridge is that there is that pedestrians would have to walk an extra mile to get across the highway without the bridge.  It's that isolation from other intersections that makes them so safe--even if someone wants to harass you, they are going to have to drive all the way to the next exit, then all the way back to the bridge (and then find the bridge, which usually is not easy).  But the purpose of this bridge wasn't to shorten time, it was to get pedestrians across the road AT the intersection.  The ramps rose from the sidewalks right along the roads, and anyone sitting at a light would have nothing to do but stare up at you 30 feet away until the light changed, and if you had to run, the ramps land right there next to the road.  Still, it was late at night.  There wasn't a lot of traffic, right?
 
I'm just getting started.  On one corner, at the end of the bridge on the east side, not 20 feet from the bridge, was a McDonald's.  The drive-thru windows looked right out at the bridge.  It was RIGHT THERE.  On the other side of the bridge, just a little farther away, maybe 200 feet, was a big bright 24-hour convenience store cum gas station.  Across from THAT, to the south, was a frikking fire station!  Completely impossible.
 
But I drove by slowly and looked at it.  I was really not happy with having to leave a bridge un-walked.  My rule has always been I can leave my clothes anywhere on the ramp.  Usually at the bottom, but doesn't have to be.  It was very late by this time, well after two, and the traffic was very sparse (although there were still customers at the convenience store).  It would only take me a few seconds to run from one end of the expanse to the other.  If I left one set of clothes at one end, then ran across, I thought I could do it.  Even this was going to be crazy, because ANY car passing by would have an open view and easy access to me--no buffer at all for them to get to the bridge itself.
 
This was insane, but I thought I should at least go up there and scope it out.  I parked in the corner of the gas station parking lot, just a few feet from the beginning of the ramp up to the bridge.  I didn't take my hat, because it makes dealing with your shirt awkward, but I brought my extra shirt and shorts.  I had one pair of loose, comfortable shorts and one pair of skin tight shorts.  I was wearing the loose shorts.  I set the tight shorts and a shirt on the surface of the bridge where the ramp stops, and kicked off my sandals.  By this time it was starting to get more windy as well, and the lightning was way closer.  I put my keys on top of the clothes to weigh them down, and headed across the bridge toward the McDonald's.
 
This end of the bridge was just insane.  The McDonald's was brightly lit.  I was right above the street sign telling drivers whatever the special was (I realize now that I never even read the sign, I had more important things to worry about).  And as I said, I could look right down into the drive-thru windows.  One grace, the restaurant seemed to be closed.  At least, there were no customers right now so it was completely silent and no one was visible inside the restaurant (although the inside was still lit brightly).  (The far side of the bridge, where the car was, was a little better in this respect.  Although the convenience store was brightly lit and actually had people getting gas right then, it was a few hundred feet down the road from the corner, so where the ramp landed was actually fairly dark.  But the convenience store was RIGHT THERE.  What I was contemplating was going to happen with several people milling around just a few hundred feet away, awake, alert people, not the darkened windows of a suburban nighttime bedroom.  If someone's awake at 2AM, they're probably on their way to or from a convenience store (unless they're doing what I was doing).
 
Then I realized I was wearing the loose shorts, and had left the tight shorts on the concrete.  The tight shorts are very hard to put on.  You struggle to get them oriented the right way, then your feet get caught in the narrow holes, then you have to really tug them to get them up over your butt.  If a car came I would have to do that while the car was right there!  I had to go back across the bridge to the clothes to switch them.  Even though I was doing this as a precaution, it meant I was still going to have to stand there naked from the waist down while I struggled to get them on!
 
I stood at the top of the bridge watching the roads.  They were very empty, long gaps between cars.  I could see a long way to the south.  I watched one pair of headlights approach, it was at least a minute from when they appeared until they reached the intersection.  To the north it seemed very dark.  I couldn't see far at all, but for some reason I just felt that there weren't many cars coming from that direction.  The problem was east and west.  I could not see the road to the east at all past the McDonald's.  When a car came from that direction, I only saw it right as it arrived at the intersection, no warning at all.  The west was only a little bit better.  I could see a few hundred feet to the next traffic light, at the corner where the store was situated.  If a car got stuck at that light, it was far enough away the driver wouldn't see me, but if the light was green, I would only have a few seconds warning before it reached the intersection.
 
But there were large gaps in the traffic, so I waited until I could not see or hear anything in any direction, then dropped my loose shorts to the ground, exposing myself once again, and tried to put on the tight ones.  It's possible to put them on quickly if you're careful and plan it out.  But I was nervous and frantic so of course my toe immediately got caught in one of the legs, and I had to struggle in the most awkward way possible to get them straightened out till both my feet were through the holes and I could pull them up.  Fortunately during that brief moment of panic no cars appeared, and I was ready.  My loose shorts were arranged on the ground like a fireman's pants, ready to jump into at a moment's notice, next to my shirt and sandals and the car keys.
 
I headed back across the bridge toward the McDonald's as cars appeared over the hill to the south and approached the bridge.  I stood there like a dummy and watched them approach, unable to figure out how to make it look like I had a reason to be up there barefoot at two in the morning, just standing there aimlessly, not walking in either direction.  The cars arrived, and I could see that even if I saw a car come from that direction, I had a lot of time before they got to the bridge.  They passed through the light, then a car came from past the McDonald's.  That car went by, and I had my thumbs hooked in the waistband of my shorts when more headlights appeared in the distance over the hill.  I knew I had a long time before they arrived, but I chickened out, so I had to wait there, milling around barely dressed at the top of that bridge at two in the morning until a new long stream of cars appeared over the hill and slowly approached.  Finally they all went by me.  Everything was quiet.
 
There was no time to lose.  It's really important to understand that you can't wait to "be sure" that the coast is clear, because the only thing you have on your side is probability.  At any moment another car can show up, and the longer you wait the more likely that becomes.  The only thing you know for sure is that eventually one will show up, so when the last car goes by you need to go immediately, even though there may be a car right around the corner.
 
I tugged off my tight shorts, then pulled my shirt over my head, and that was it, I was completely naked 30 feet from a brightly lit McDonald's, completely exposed above a huge intersection with no buffer of safety in any direction.  I jogged quickly across the bridge to the other side.  And, right as I leaned down to grab my loose shorts, a car appeared, coming toward me from past the store.  It arrived way faster than I possibly had time to deal with, and I only had one leg in the shorts when it arrived at the intersection, directly below me, not 20 feet away.  Instinctively I fell to the ground to try to make myself as low as possible while I yanked on my shorts.  Instead, I ended up positioned on the bridge on my butt with my legs spread open and my pussy completely spread and pointed directly at the car that was now sitting quietly at the red light.  It just sat there, surely looking right at my naked body, my naked pussy, as I struggled to yank on the shorts, leaning back onto my shoulders to lift my butt in the air to get them pulled on.  I still didn't have my shirt on, but miraculously, the light turned green and the car drove on.  I yanked on my shirt, inside out and backward, and I was covered again.  I breathed a huge sigh of relief.  I was safe.  I took the shirt off again and turned it right side out, and pulled it on again, then stepped into my sandals and headed down the ramp toward the store and the car.
 
I had done it!  The most insane pedestrian bridge of all time.  And so, of course, I immediately started thinking to myself, come on, you can do better than that!  I wondered what would happen if I walked all the way to the convenience store naked.  My car was in the closest corner of the parking lot, the driver's side door was closest to me; I'll bet I could have gone all the way without any trouble.  But I was just thinking.  I got back in the car and headed out onto the street, driving slowly past the bridge to admire what I had just done.

Here's a closeup.  Just a little more detail.

Here's just a basic wide shot of the bridge, the cul-de-sac on one side, the long frontage road on the other.

Here is the bottom of the ramp on the far side.  You can see how close it actually is to the highway itself!  No barrier or anything.

The storm had finally arrived, and it was raining hard, and the lightning was out of control.  Boom boom boom right on top of the car.  It sucked, there was no way I could continue.  Still, the weather had said there was only a 30% or 40% chance of rain, so I thought maybe it wouldn't last very long, and it would take me a few minutes to get to the next bridge anyway.
 
The next bridge was right downtown, not more than a mile or so from the big buildings.  There is a big interchange of interstates, on one side of the interstate is nice apartment buildings and restaurants and hotels and the downtown, on the other side of the interstate, was an industrial wasteland, a large rail yard, many lots filled with stored semi trailers, even a junk yard.  Past all this was an older, slightly run down neighborhood, and in that neighborhood is a large park with some sports fields, and another bike path.  On the other side of the park from the neighborhood is a large rail yard.  And over that rail yard is the bridge carrying the bike path.
 
Coming from downtown, there is a road that goes under one of the interstates, and just past the interstate the bike path emerges.  So, from this street, if you followed the bike path, you would go into the trees a couple hundred yards then reach the bridge, then over the bridge and into the park.
 
From this spot where the bike path emerged right next to the on-ramp to the highway, it would be the best place to get up to the bridge.  The problem was, this was a road in a totally industrial area.  Absolutely no reason for a car to be parked on the road right there.  It would stick out like a sore thumb.  It would probably have been stripped by the time I got back!  Also, it had the same problem as the first bridge tonight, on the far side, if I left my clothes before coming back to the car, I would have to walk all the way through the park to get to them.  I decided it would be better to do it the other way around.  Start in the park, walk over the bridge, drop my clothes at the end of the bike path where it emerges onto the industrial street, then head back to the park naked.
 
I had the same problem I mentioned before, I didn't want to park in the park's parking lot, because it would stick out like a sore thumb, so I parked on the street that bordered the park.  On the opposite side were small houses.  It was 3:30 in the morning, but one of the houses still had lights on!  Still, all was quiet.  Fortunately there was another car parked on the street outside the park, so I parked right behind it, so my car would not stick out at all.
 
It was raining hard now, and the temperature had dropped precipitately.  It was now below 60°.  As soon as I stepped out of the car I was soaked.  This was insane; I was shivering before I'd walked a hundred feet into the parking lot.  It was crazy.  I'd never make it.  I should give up, come again another time.  But I didn't want to give up.  I could make it, and there would be the wonderful warm heater to greet me when I got back.
 
The parking lot was quite deep, several hundred feet till you reached the grass of the fields.  The bike path ran along beside the parking lot, and I stepped onto it and started into the park.  It's a long, deep park, just sports fields with trees on every side and the bike path heading to the end, at least a thousand feet away, at which is the ramp to the bridge.
 
It was raining insanely now, and cold, and the lightning was flashing violently, it felt like about ten feet over my head.  About 200 feet in there were a few trees, and a picnic table, and I didn't want to walk all the way across the bridge with my clothes on, so I took them off right there.  The parking lot had a couple lights, but the street was dark.  I couldn't see my car.  I piled my clothes on the table with my sandals, then hid my keys under a tree on the other side of the bike path, and I was naked in the middle of this vast empty field, no protection of any kind for hundreds of feet in any direction.  The rain was streaming down my naked body, and I realized I was no longer feeling cold.  It's an amazing thing about cold weather that no one realizes unless you a strong enough person to walk naked, that you don't actually need a coat.  In fiction it's always depicted that the person was in the rain and got a cold; that's the opposite of what happens for strong people.  You warm up to it, and it was comfortable and nice, even 58°, naked in the pouring rain, I felt wonderful.
 
I continued along the bike path toward the bridge.  This bridge was a cool one, on either side the ramps were spirals, so for a moment, I was out of the rain as I went up the first loop.  The bridge itself was very very long and exposed, no obstructions of any kind for hundreds of yards.  The only disappointing thing about it was that there was no road under it.  I was actually completely alone and in control.
 
As I started across the bridge, I felt the need to pee.  I have peed while naked before, of course, but usually I squat down like I would camping.  But I decided, why bother?  It was raining so hard, even if some got on me it would wash off in no time, so I did something I have never done before, I just peed as I walked.  It was so awesome!  It's an unusual thing to do, so it took several steps before it would come, and then I felt it wash down over my legs.  It was so warm, it felt really nice!  It's weird to say, I actually quite enjoyed it.  I just kept walking across the bridge as the pee streamed down my legs like a warm bath.  This was definitely something I was going to have to do again.  I peed for many steps across the bridge, the lightning flashing overhead, the thunder, the pouring rain, and so high up on the bridge, I had a commanding view in every direction.  Stretched out to the right was the interstate.  It was not close, but any cars going by would have a clear view of my naked body if they happened to look, and in the distance to my left I could see the tops of the tall buildings of downtown, somber and powerful against the flashing sky.  I wasn't the queen of the night, I was a goddess.  I could do anything.  I was the most powerful person in the world.  With the storm crashing above me I felt like Prospero summoning the heavens.
 
The pee stayed warm on my legs for several minutes until it was washed off.  At the far end of bridge the ramp spiraled twice around.  It was right up against the on-ramp to the highway, just a few feet away, but it was an express lane, so it was closed for the night.  I was out of the rain for several moments, then came out on the path out to the industrial road.
 
At the end of the path, I put down my extra shorts and shirt, and stepped out into the middle of the quiet road.  I looked both ways, up the incline of the road back the way I had come, and down under the highway toward the city.  What if I just kept going?  I had had enough, though, so I headed back up the bike path, leaving my clothes in a pile on the sidewalk.
 
The storm continued to crash and flash all the way back across the bridge, and cars sped by on the highway from time to time.  Back in the park, I walked, naked in the rain, invincible back to the picnic table.  It was time to stop.  I considered walking all the way back to the car naked, but there was no need.  I put on my soaking wet shirt and shorts, grabbed the keys, and headed back to the car.  (I know it's not a big deal, but it makes me proud that I can hide the keys in the pitch black and find them again ten minutes later.)
 
The car was still warm, the heater blasted and warmed me up again in no time.  I headed back over to the end of the bike path and my clothes.  On the incline down to the bike path, I met a woman on a bicycle, in the pouring rain, maybe crazier than I am!  Is it possible she was just on the bike path?  What a disappointment!  How great would it have been to encounter her there!  My clothes were still there, soaking wet.  I retrieved them and headed home.
 
There were a couple more bridges that I might have tried quickly if it had stopped raining, but it was still pouring, and it was after 4 o'clock by now.  This had easily been the longest naked walk I had ever been on.  It had to have been well over half a mile.  Wonderful.

Here is a closeup of the trees along the path.  This picture is a little bit old, because it looks like that was a tent, probably for a party of something, but now, where the tent was, there's a picnic table.  That's where I left my clothes.  Then in one of the trees on the far side I hid my keys, then continued off the picture to the right toward the bridge.

Here is a closeup view of the bridge.  As you can see, the bridge is very long and very exposed, but it's just over a torn-up rail yard, so there was virtually no danger of being seen.  The interstate went by past the far end of the bridge, and the vehicles there were easily visible, but in the dark and the rain I don't know if they would have been able to see me even if they had looked.
