I've been helping at the local bicycle co-op for the last 4 months. I originally had high aspirations of donating some time to a worthy cause, but I soon found out I had a dark, selfish side to this venture.
I learned an enormous amount about bike wrenching and also about older bicycles... so much so that I'm now kind of hooked on the activity... I no longer go for the high aspiration reason, just for the fun aspect.
Does anyone have a volunteer story? Bike kitchen? Bike co-op?
