So it seems that I've had more and more conversations with people while biking around northern VA that start out like this, “So your biking around to save gas money?”

    To which I usually answer something pretty consistent with, “No, not really. While it does save money by not using gas to get around, I haven't ditched my car, which is necessary to save a lot of money by bicycling. I bike mainly because it seems to be a better use of my body, has less of an impact on the environment than driving. And in the back of my mind I'm really very worried that a worst case 'peak oil' scenario would leave me unprepared to support my family if I didn't do this regularly.”
