BTW - Glad to see we didn't completely scare you off. Riding fixed is something that will help you out in every aspect, not just riding your bike. If you drive a car, I can pretty much guarantee that within a few months you will have a much better understanding of traffic, and how to predict it's movements..
Actually the biggest thing I've noticed, and only after a week, is that my "circles" are better on my road bike. I've probably picked up 1mph just because of smoother pedal stroke! I am going to add one day a week fixed as part of my training program. I'm adding some things to the bike, everything should be here by the middle of next week. Bullhorns, different seat and the rear brake. I'll post some pix when it's done.
As for the fashion question I wear my road kit. I was just wondering about all of you guys who are riding in street clothes cause I would be really uncomfortable if it were me. Right now I'm a stay at home dad but my wife really is missing the kids. If she decides she want's to swap "job" I'll be using the fixie as commuter bike and that will most likely get me into wearing street clothes with a cycling specific under-short.
