This was Part 2 of a "Test My Gear Close to Home" camping experience.  It's close enough to the wine country aspects of Napa to be an easy overnight without the excruciating Napa Valley hotel prices.  Google doesn't like finding the entrance, but I got the street address off the website and eventually made it.  The gentleman at the gate was lovely; the camp hosts kept to themselves.  My only drawback was that the showers were foul (cobwebs and spiders everywhere).  It's very quiet and woodsy.  I couldn't see my neighbors.  I was awoken (as is the norm in NorCal) to gobbling turkeys at dawn.  Easy access to hiking trails.  A shuttle stops at the park to take people into town for dinner if they don't want to drive after drinking.  The ground is volcanic rock and super hard in the dry weather.  I broke a couple tent poles and couldn't pull the rest out of the ground, so they're now donations.
