I actually rode 'round a blind corner on my bicycle as a kid, and hit a tree and went right over the handlebars into the tree...but, as I said above, nothing much ever happens to me, even though I used to climb every tree in sight! I don't think I was even scratched. Gee,I hate besmirching this tragic thread with tales of how I DON'T get hurt....what are you injury prone folks doing?
