I commute in NYC. I started because of the typical reasons, fitness, environment, but I have to say one of the major factors that keeps me going and keeps the ride frickn' fantastic is all the beautiful people I see (when I say people I really mean woman). On bikes or walking. Espicaially this time of year when so many relish in the ability to shed as many layers of clothing as possible. Just pay attention not to run into those parked cars.
