When I was a kid bombing around on my Schwinn Spitfire with my buddies, there was an "old man" who rode a Green English Racer around town, to and from work, wore a coat and tie, dress shoes. As kids we all thought he was weird. Now turning 60, I think what a great guy that "old man" was, what stories he could have told. We'd watch him always keeping our distance, he's stop and talk to his friends, old retired guys sitting on park benches. Here was a guy who was still active, riding his bike, working and interested in life.
Here's to all the 70+ folks riding their bikes. I bet if you asked them they wouldn't feel like they were 70. Hey I'll be there myself in a few short years.
