    "Mill Valley is Dog Town. The dog parks are the best in the world right along the bay. Shop owners have water for dogs; many have treats for them, too. We have thousands of dogs here!"

    "The neighbors are friendly and the views are great. this neighborhood is positioned in the middle of the Dipsea, Cypress, and Old Pipeline Trails, so running, hiking, and biking is just out your front door. In the center of the neighborhood there's a large permanent designated Open Space Park Area that used to be the Old Mill Valley Reservoir that people, kids, and dogs walk and play in. Their are only 12 houses on the private road, so there's not a lot of traffic and it's quiet and peaceful. Once a year there's an annual neighborhood block party at the end of Edgewood Ave. "
