So, we're starting to make that plunge towards conserving our automobile use. As you may be aware from previous episodes, Amy is already a telecommuter, so this one falls mostly to Rhett. Just by taking a bike for his daily commute and changing his lifestyle around slightly (read: no going home for lunch), he's able to carve off a good 90 miles a week. That might not sound like much, but he really doesn't drive very much as it is. If we're not going on a road trip (which is rare), then that's probably at least a 50% reduction.Commuting and running errands with a bicycle is pretty easy. Just hop over to t or your local bike shop and get a nice, sturdy, used bike...then replace the mountain bike tires with slicks designed for use on the roads. A couple of small and simple tools to go with it, and you've got a vehicle that's mighty fun, healthy, and green to ride.Oh, and did we mention it's the most energy efficient mode of transport?
