I think you mean the San Francisco area, which, yes, is terrible once you have a family. South Bay (Cupertino/San Jose) and deep East Bay (Fremont/Castro Valley) are relatively safe areas with several good schools. I don't have kids or live in the Bay Area anymore, but I know many people who grew up there and still have younger family growing up there.
