May I suggest Golden Gate Park? Good cover. Lots of forage. Plenty of animal huggers to protect them.
Griffin Park would be a good second choice.
Maybe a few in Yosemite & Kings Canyon, or Mount Diablo.
Since California even has one on its state flag, it just seems fitting.
In fact, a pair of them loose in the halls of the state capitol building during a legislative session has been a dream of mine for decades.
You are funny. Loved that Golden Gate Park remark.
