I have been riding my bike to work everyday since the beginning of the year and I love it. It's great to get a little exercise right before and after sitting at a desk for eight hours a day. I occasionally run into people I know during my commute, and because I'm not in a car I can stop and talk. It's a much less isolating way to travel. It's also a great way to learn just how nasty automobiles really are - you don't know how gross your exhaust is until you spend a few stop-and-go miles behind someone driving a car.
