That's awesome that you chose the more wallet and environmental option. I have a dodge dakota and a kio rio - I ride my bicycle to work every day [about 8km] and back. The truck is for hauling stuff and camping with kayaks, and the rio zips me around to the north end of town when I need to.
About bike riding and losing weight! I have a story to tell fo sho. I was 220lbs at one point - at 5'7, that makes me a little tub of blubber. I sold my car, and stopped snacking when I was bored [really, it's a common thing to do]. I started riding my bike to work and back which at the time was about 3-4km after a 40 minute bus ride, which was good for 10 months of the year [vancouver rain]. In a single year I dropped 60 lbs. I'm now 165. Now obviously you aren't gonna ditch your scooter, but early on you did say chunking down was on your list of things to do - how did that work out? Or is it right after your next arcade project?
