Hoped I would never see a motorcycle accident occur but did this afternoon. Young man was at the red light waiting for it to turn to green. The road had aN incline. Light turns green, young man leaves everyone at the light, tries to lift the front end of the bike off the ground to do a wheelie. HE DID NOT COMPLETE HIS WHEELIE. All cars stop and watch the motorcyle roll over and over - young man is thrown from the motorcycle - he rolls over and over - wearing shorts, tennis shoes and a t-shirt. He was lucky that the motorcyle did not roll over him. He got up limping and tried to lift his bike from the pavement. NO LUCK. Bystanders moved his bike from the road and he went to retrieve (from the road) one tennis shoe that came off. Will they every learn.
