    "Having lived in Mill Valley for thirty years, I have to agree with the many sources, including the Smithsonian, who rate this the best place to live in the country. Small town ambiance, ten minutes to San Francisco, a half hour to the wine country. Lots of local culture--theater and music venues abound, with plays, comedy. ballet, opera, and anything else one could desire. The only drawback is the cost of housing."
