    "This is a quirky, "with-it" small town. Truck drivers and farmers mix with professionals and commuters to support Penngrove School, the local club house, and Penngrove Park -- privately owned by a home-grown non-profit. Great place to raise a family. "

    " Private development of homes on acreage nestled among hils around a year-round pond fed by area creeks. 10-15 minutes to Sonoma State, Cotati and Rohnert Park shopping. Quick access to 101 via Petaluma Hill Road and/or Rohnert Park Expressway. This is a rural area where most residences have livestock. The roads are private with low traffic making walking and bicycling enjoyable. There is a multitude of wildlife."
