A friend of mine was asking for ideas on secluded overnight drivable spots around the San Francisco bay area, within about 1.5-2 hours (2.5 tops). I have a few ideas (near henry coe, etc), but want to give the best options, so i'm checking with you all in case anyone knows great spots. Feel free to reply by PM if you'd not like to make your favorite spot public:), and i don't mention it publicly either.
The specific criteria: dark to see the stars very well, and private enough to sleep in the car at night without others being nearby, or worrying about rangers coming by, etc. I think things like access roads are all fair game if they're open and legal, and have a good view. Basically, an area similar to what Harden Flat near the valley is like, but without others around.
