I had a skateboard for about 30 minutes. My folks live right at the top of a pretty steep hill in Bloomfield. So I got ont the board and headed for the bottom. Then I quickly learned that skateboards were meant for tricks and rolling on sidewalks. But they don't do well with speed. Mine was violently shaking and I had enough of that. So I tried to step off of it and let it go. Might as well have been jumping out of a moving car. All I recall is laying in some old lady's yard for at least 30 minuted before I could get up. Now if I had been watching someone else do it I'm sure it would've been hilarious.got going down a hill in the neighborhood going a good 30 mph and slamming on the rear brake and power sliding..until i did it one to many times tire blew out and sparks and ohhh face first into the hay bails in the neighbors freshly landscaped yard
