@ Chicada & PelesTears- I live in Santa Monica and my city is very sustainable. We have had a sustainability initiative for as long as I have lived here (before 1998), and public transportation, social equality, and pedestrian friendliness are big parts of the initiative. We also have a nice pedestrian shopping district in the 3rd street promenade. It is a sort of outdoor mall with eight parking structures that encircle the promenade. The promenade is a big part of the city's economy and it is a nice focal point of my city. It adds character, and infuses Santa Monica with culture. I agree that a city should focus on making itself walkable because it benefits the environment, the local economy, and makes a city livable.
