I started commuting for fitness. But, then more reasons to continue surfaced. Saving money by not owning a car to get to work (about $6500 a year which I would have to earn over $10,000 before tax to have $6,500 left over. Thus I consider my bike a $10,000 raise!). The environment, the enjoyment etc. As well I have begun to hate cars the more I ride. I guess that is the natural evolution of bikers, we begin to hate cars the more we ride!
