So either the map was wrong or we were totally lost, but one of the roads we were supposed to take just ended in the middle of nowhere with 2 dirt driveways. So we went up Highland Rd and that turned out to be pretty fun, it led us to the top of the mountain, near the Loma Prieta summit, we could see both Santa Cruz and San Jose. Those roads were lots of fun though, definitely should be driven more often.
