What? You think a little ole broken bone is reason enough for cancelling your registration for the greatest dirt bike event of the year? No way, bud! Suck it up-- you still have a couple weeks to heal-- by then it will just be feeling sore, and you'll prolly be wanting to ride again anyway. ;)
Sheesh, you're practically living in Cooperland's backyard anyway. Might as well stop by and say "Hi"!
I'd still be going, even if my bike was in 100 pieces and both my legs were broken. I need the vacation!!!
