    "Dog owners will be very pleased to live in this community. There are many pet lovers here. The only area of concern is there are wild animals living in the area; coyotes, bears, bobcats, skunk, opossum, rattlesnake and deer. Dogs and cats should never be left unmonitored in their yards, as they may be eaten or injured by coyotes at any time of the day."

Kindred spirits on my block. Artists, professors, scientists, media people, animal lovers, gardeners, hikers who prefer maintaining a low profile and quiet simple and more authentic lifestyle raising children and enjoying grandchildren."
