well, one of the best stories I have heard (Readers Digest??) was of the two young women hiking in a National Park...they came to a tent with no one about, but hearing faint noises, looked over a ledge to the nearby river, where, in the distance, two men were swimming/bathing, their clothes, camping gear and--camera-- piled in front of the tent......The girls looked at one another, a wicked smile appeared...and quickly they both stripped, took each other's picture with the guys' camera, replaced it as they found it, and went on their way....
