Just an update on this. We never found the campground in SF that we'd seen in photos. Maybe someone was just parked at one of the pullouts up above the bridge on the mountains.
But we loved SF so much! Spent lots of time in their great Golden Gate Park, etc.
We found the fairgrounds at Santa Rosa to be a good deal for California- and just drove in to SF.
