Yeah there is a bunch of people that ride in SF most everyone is older you and me might be the youngest people around. Stop by 1977 mopeds on 16th and mission right across the street from the bart station, they sell some bikes and can also help you out with questions. Anything you need really. And Elliot is awesome, he is really nice and i know he will give you a good deal on any bike and can give you a few pointers and info on moped stuff. Good luck. I will be back in SF for spring break as well on thursday. E-mail me if you have any questions.
