MP, go forth to Fixed Gear Gallery and Velospace and find inspiration. Visit some big cities and big city bike shops. Take a Greyhound to Toronto and check out Curbside Cycle and the Urbane Cyclist. You've got a lot of hills where you live, I would stay with a lower gear and run a front brake at least. Maybe hook up some cross tires, it looks like there's a lot of good trail riding to be had. Are you going fixed or free? Anyone else in your town riding fixed?
