Here in my old age (52) I'm pretty much just an all-around bike guy these days. I've been commuting back and forth to work everyday now for four years, and the last six months pulling a trailer I built. I do all my around town, commuting, going to the store visits by bike, and 4-5 days a week I engage in a ten mile hammerfest on my classic road racer.
Right now I only have two bikes, and its enough for me just to keep these two on the road.
