I was walking my dog and tossing a tennis ball. My 4 year old daughter at the time and was pedaling her bike around. Somehow the ball took a one in a million bounce and wedged itself between her front tire and the street. She was riding fairly quick and flew off the bike and had some nasty road rash on her face. Took over a month for the scabs to finally heal.
No one but me knows what actually happened...I'm still "not sure" how she fell...especially if my wife asks.
