My only crash....
Training ride while I was in college. Coming off a big hill, spinning hard on the big ring, my training partner starts to pull over for me to pull through and changes his mind. Wheels touch, I do a face plant and roll. No helmet. Training partner finds a house nearby and uses the phone to have his sister come get me and we go to the University of MO med center. Get stitches in the mouth and face, doc said he stopped counting at 40. Scraped the palms of my hands (gloves torn off) to where I could not use them. Scrapes on my shoulders (jersey trashed). Went back home for a week and visited my LBS. Owner takes one look and asks if a truck hit me. I had hypertrophic scars on my shoulders for years afterwards and still can feel the scar in my mouth.
Ahhh those were the days.
