I wasn't sure if I should post this in Transportation or here, but finally I decided its more of a community development thing.
A group in Oakland is running a Car-Free Challenge for the month of June (more info is at (http://www.transformca.org/live/car-free-challenge).
It seems a pretty interesting idea for community organizing around livable cities. Anyone ever seen anything similar in their communities?
If anyone is in the bay, I'd suggest signing up, and if not, supporting someone would be awesome too (I'm doing it).
