Whoo, that's intense. I suppose it's only a matter of time before I can contribute something good to this thread, nobody really gets away without a major crash sometime in their life.
As it stands right now, my worst crash would have to be when I was 8 - bombing down a 6% grade on my orange and black Huffy. Freaked out in the middle of the hill and mashed on the front brake. Flew over the bars, landed in a sprawl on the pavement. I got a huge bloody scrape across my sternum for this awesome bleeding-heart effect that seriosuly freaked out my mom.
