We started at a winery that is associated with the Jacuzzi family!
They had a tasting room and lots of stuff to sell. I thought this oil/vinegar combo was cool.
There was a simply ancient grape vine, probably half a foot in diameter at the base.
We went up to Glen Ellen for a chocolate tasting room that wasn't open and found the Sonoma Development Center, one of California's oldest institutions for the mentally disabled. The state is phasing these places out, but it is a very sprawling complex, with architecture from an eclectic mix of California history.
From the 1880's main house
To mission revival
to 1960's modern
My camera didn't pick these up too well, but they were really pretty at the time
