Napa Valley, just north of San Fran, is the home to wine making in California. Our first couple of nights were on a site surrounded by some of the best motorhomes in the world called Prevost. Out of a total of appx 30 pitches, 6 were occupied by these monsters which cost $2,000,000+ !
There’s a great Petrified Forest, definitely worth a visit. There’s also, one of 3 geysers in the world called “Old Faithful” . This erupts every 30 to 4o minutes.
