so i'm riding thru the park last evening, on my way home from getting a burrito (mmm) and cruising along pretty good on the little asphalt bike path... i come up to a sharp turn, but figure the knobbies on my mtb can handle it. well, what i didn't see was the small puddle of water i was about to corner thru. my back wheel skidded out from under me and i went down on my side, absorbing most of the impact with my chin/nose/mouth. there was a lot of blood. i got home and realized i had bitten almost completely thru my lower lip, right under my soul patch. dang. just thought i'd share. any other similar experiences?
