True story, I swear, as unbelievable as it sounds. We camped at a riding area one weekend. We got up on the second day, and decided to swap air filters, because the trails were dusty. We're all merrily wrenching away, and suddenly, one of the guys screams as he is throwing his seat and running away from his bike, screaming "Snaaaake!". So we all cautiously walk up to the bike. Sometime during the night, a small rattlesnake had somehow crawled inside his airbox, and was staring out at us, quite upset.
