I guess I'm older than i thought! I realize that my own parents (if they were still alive) would actually be the same age and generation as many of your grandparents! Oh well.
Yes, I should not generalize. My own parents were real hippies, only back then they were called "Bohemians", and when I was young they were called "Beatniks"...(God I'm feeling older by the minute!!)...

As to my own biking supporter- well it's certainly my darling DH- he is my mentor, my personal fan club, my best friend, and my inspiration. I feel so lucky to have him. He's been quietly biking once and a while by himself for years, but since I got interested, my enthusiasm has infected him as well, and we share the raging biking fever now. He patiently shares his bike knowledge whenever I ask him, but never does it like he's "educating" me. He helps me learn to fix and adjust my own bike. He never feels we need to compete in any way, never speeds on ahead when we ride together, though I know he could. A truly wonderful person.
