As the title suggests, I just returned from a week's trip in DC. I was very struck by how little people rely on cars there. I know this is fairly common in most east-coast cities, but it was definitely a new approach for me to walk and take the Metro everywhere. It's the most exercise I've gotten in years . Does anyone think we'll ever be able to reach that level of development/density here in the midwest/southwest? It sure would be nice, I think that'd tackle obesity, part of carbon emissions, and fuel prices all in one go.
