Zactleeeee.
Then there are hidden gems like the Pulgas Water Temple and its sister site in Sunol, right outside Fremont.
If someone goes to the Pulgas Temple, might as well go to Filoli Mansion for art and ither stuff,
Little known tidbit: Filoli is the mansion used as the home for that great 1980’s TV series “Dynasty”.
Also the home of the main character (Michael Douglas) in the 1997 movie "The Game."
