One of my earliest memories is an ambulance taking away my mom when she was teaching my sister to ride a bike, and slipped on gravel. This was probably around 1957. I remember them saying that she broke her hip, but she told me later that it was not broken.
She also taught me to ride, which involved pushing me to get me started, at which point I was on my own. I remember it clearly.
I remember that the entire family went for a bike ride picnic once.
