One of the major complaints I have always heard from anyone I know who has lived in the Bay area is that the commutes there are terrible. Even on the weekends traffic can be horrible from what people have told me. When I was in San Francisco I was lucky enough to be able to stay at a hotel and walk wherever I went. But two friends met me for drinks downtown and had to drive 45 minutes just to get to the BART station nearest to where they live. They hate the traffic in the area.
