I just about got run over by a truck going 20 KMH. I was riding my bike down a RV park road when I didn't see this truck coming. i hit the brakes and my bike swerwed and threw me off it. I gashed my elbow so bad, I couldn't move my arm for the day. (Accually, 5 hours, until dinner of burgers =] )
I am scared to think of what would have if i had hit the truck...
(BTW, this was 3 years ago)
