I havent, but while running at Cross Country practice, one of the kids got hit. We were all running down a wide sidewalk, 4 wide, and this guy on a MTB was headed toard us, just some old guy out for air calling it 'excercise', so we all move to one side to give him room, and he doesnt move any and right as he gets to us he swerves into the group taking down one of the guys and himself. It was hilarious cause the guy flipped over the handle bars, and our guy was totally fine, he got up cursed a bunch at us and rode off. Lets just say the laughter from the rest of the run made it go by like 10 times faster.
