Did your parents support your bicycling when you were a child?
Absolutely. And they still do. Both my parents have cycled since they were kids, continued to cycle all while I was growing up, and still cycle now that they are in their 70s.
I grew up surrounded by bicycles. My father always had a basement or garage full of bicycles and bicycle parts. He built and repaired bicycles for various people in the neighbourhood. The house was always full of bicycle bottles, bicycle clothing, and Bicycling Mag when it was good.
When I got into Randonneuring about 12 years ago, my father also got into Randonneuring. He not only supported events, but rode some with me, including a 300K randonnee.
When Rowan and I get to the Canada portion of our Round-The-World mostly-cycling trip we're currently on (we're in Germany right now), I hope that Rowan and I will be able to ride with my father (and possibly mother too) again.
