Naaaaawwwww ...... everything I'd spend on gas I end up spending on extra food ... OK maybe I spend some of it on frivilous extras for the bike, but a happy bike is a healthy bike!

On the other hand I save a lot ($150/month) on parking, even more ($200/month) on insurance and registration fees, and I'm guessing ($150/month) on maintenance, tires and tune-ups)
