2 Mile Challenge
Found this cool tool at The Deets. It's a map-generator that lays out a 2 mile radius from your home (or any address you enter). The idea is that most of our commuting takes place close to home - and couldn't we bike or walk - or use some other fuel saving mode of transportation.
As I may have mentioned before, I've tried to do more bike errands. I'm limited by weather (yes - I know not everyone is), and by the fact that many of my short errands involve ferrying kids around - often at night. Bike purists would see those as very lame excuses - but I don't really care. On the other hand, the map does make me pause and wonder what I can do by bike. Maybe I need to accessorize (or pimp my ride) with new baskets or something.
