I've peed in dozens of places, but my favorite and most daring would have to be in the backseat of my friend's car without her knowing (she's into pee as well, and had stated numerous times that she loved having people pee in her car), the movie theater in the back row, on a blanket in a tent I was sharing with someone during a camping trip, at an old friend's house while they were sleeping, and at a bar against the counter.
