Walkable Communities, Inc.
"A non-profit corporation ... organized for the express purposes of helping whole communities, whether they are large cities or small towns, or parts of communities, i.e. neighborhoods, business districts, parks, school districts, subdivisions, specific roadway corridors, etc., become more walkable and pedestrian friendly."
See especially the Walkable communities by region section by Dan Burden.
I am ecstatic to find this... While I value the "carbusting" approach... I'm not too motivated to work that angle. Walkable communities on the other hand... Maybe in the future I'll be working more with walkamerica, walk21 and the like!
In addition, Dan has started a walkable communities listserve.
