Yeah, good question. I just converted a bike to a singlespeed to use as my "go anywhere" bike. But it has rapidly moved up the charts and is now my main commuter. And when I'm hitting these hills, I'm sort of wishing that I was clipped in. But then if the bike had clipless pedals, I'd have to go and find a THIRD bike for the around-the-neighborhood jaunts.... You see how quickly this spirals out of control.
