I had a friend that smashed a deer broad side. yes, a deer. Apparently he was riding down a hilly wooded bike path around dusk and well, the deer wanted to cross the path. He wasn't really sure who scared the sh*t out of the other one more when it happened. The deer ran off and he was left with a nice size dent in his top tube from his bars flipping around. He was just happy not to have gotten kicked.
