When I was about 10, we lived on a street on a steep hill. The road took a 90 degree turn at the bottom of the hill, where there was a barbed wire fence. I got a metal wheeled skateboard and started down the hill. Well over half way down I realized that I was going way too fast to make the turn or to jump off without getting hurt. So I crouched down and sort of sat down on the asphalt just before the turn. I tore the seat out of my pants and still ended up in the barbed wire.
Our Generation INVENTED SKATE BOARDS! So much fun!
