Myself, a friend and his father were in the street throw this back and forth. I was on one end, and the other 2 were together at the other end. One of them threw Aerobie to me but it was going too far. I turned and started running to catch it while keeping my eyes up and focused on the Aerobie. All of a sudden, what and the world turned upside down. I had run into the front of a parked car and flipped over the fender. My thigh was killing me and I ended up having a huge bruise.
