DISCLAIMER: Racing dirt bikes, like snowboarding, karate, trying to move a large cat from her favorite chair, and teasing a small dog with that last bite of hot dog, might mean you will be tasting salty blood before sunset. If you are not prepared for the pain, stay home on the couch where it's safe and watch WWF, Roller Derby, NASCAR, or something equally inane. Never say "Watch this!" it is usually followed by disaster. Understand that you will crash when pushing the envelope of your abilities, it is not a question of if, it is a question of when. (Or in my case, how many minutes from now. : )
Leave your ego at home, use your head, wear all the protective gear you an afford, and always floss after meals.
