I remember where I started riding, but not exactly when. It was in the alley at the first house I can remember, my Dad pushing until I got it. I believe we left that house between kindergarten and 1st grade so that would put me right about 50 years of cycling. That bike was a quite big for my age banana seat single speed and lasted until high school (morphing into bmx look along the way), then I got a 10 speed that lasted until mid 30s.
