Car Free in SoCal

Can anyone live car free in Southern California? Apparently so. A family in Santa Ana has. Here is an article on their transformation from car poor to car free. They now bike just about everywhere. They utilize public transit also, and once in a while rent a car. They also have a blog about their car free journey. I believe that this type of shift in thinking is what will make our world a better place for everyone, not the thinking that everyone deserves a car and only adding more roads will cure our traffic problems. Because we know it won't.
