1987 attending UC Davis. on my 12-speed, heading to class. very "bike-centric" culture on that campus and surrounding area, so i'm zipping along calling out "on your left...on your left" as i rode through campus, passing like i was in the Tour de France. on a long straightaway, right in front of the big lawn on the Quad, a girl on a beach cruiser decides to stop dead in front of me to make a LH turn. i plowed into her going about 20 mph, and flew ###-over-tea-kettle when my front tire demolished her rear tire. got up off the bike lane pavement, and started berating her with all kinds of obscenities at a volume that brought a hush to most everyone there. after about 15 seconds of this, and taking a moment to realize what i was saying and the reaction of the girl (unhurt, but crying) and the crowd (death-stares coming hard), i picked up what was left of my bike and walked to class with it over my shoulder. instructor sends me bruised and scraped to the Campus Health Clinic, where i was diagnosed with a fractured wrist. looking back, i was obviously the "embarrassing" part of that injury.
