Used to go parking in the Lovers' Lanes when I was a highschool kid. After my girl and I were done fucking, I'd just pull off the condom & drop it out the window onto the ground.
One of these Lanes was on the border of a park. Went to the park with my Weimaraner once, and she wandered off into the Lane. First time I'd seen it in daylight with no cars. (There was space for about 20 cars.)
There must have been hundreds of rubbers lying on the ground. It looked to be wall-to-wall condoms -- and most of them were just basic Trojans (the ones in the red box), judging by the color of the latex.
I'd go double-parking with a friend and his girlfriend du jour. It was just a contest who could get laid the most times! It took almost no time for the four of us to get naked after he stopped and put the car in park.
I especially enjoyed hanging my sweaty naked self over the bench front seat (it was his '55 Chevy BelAir, so he drove; I had no problem with that!) while he was screwing his girl and saying, "Hey, Chris, I need another rubber!" He kept up to 36 of them (unboxed) in the glove box. As often as not, he'd reach in there one-handed (and without interrupting his fucking) and toss me a group of 6.
