Apparently in Florida, they pee on trees. If you look hard you can spot them doing it at night.
Honey, they pee on trees everwhur. Some fools will even pee on an electric fence just to see it it's really electric.
When I was growing up in Texas, if somebody needed to pee, they would pull over, crouch by the side of the road and squat, hiding behind the door to the extent possible. A friend of mine related that when she was a little girl, she couldn't do it because someone would see her. Finally her granny told her, "Just turn your butt to the highway. All butts look alike," and that worked.
