    "Tam Valley is what Mill Valley used to be like...quiet, green, beautiful, uncrowded, close to trails and offering a quick back road to the highway. 18 minutes to the SF on a fast day, 3 minutes to downtown Mill Valley or Mt. Tam's trails."

    "Used to live in this area; now live in another area of Mill Valley, have worked near here for many years. This area is a great commute to SF, hiking, beaches, and only a few minutes drive to downtown Mill Valley. More private and quiet than the close to town properties except those way up the hills. Great school in neighborhood and recently redone park with play area, picnic and tennis. "
