peeing in bushes
You have to ask why boys (college boys) pee in bushes, and college girls don't? I'm sure if the college girls had this thing dangling in between their legs.. and they could easily pee without dropping their drawers, baring their asses while squatting, well we would be hearing about underage college girls being caught peeing in bushes. Seriously, its as simple as that.
When my kids were young, and we were out in the woods, hiking/camping etc. it was nothing for my kids to go behind a tree, or a bush and pee. On the highway, we have stopped, ran in the woods and left the kids relieve themselves. I guess the moral of the story is first off, dont drink underage. If you do, dont make it so easy to be caught by peeing in a bush, especially when you could have probably held it till you got back to the dorm considering having only drank 1.5 beers.
