Overnight parking that is actually legal

Six pullouts and lots along the central coast where sleeping in a van is permitted rather than merely tolerated, with the exact signage to look for and the ones that get patrolled. Two are Forest Service land where dispersed camping is legal by default, three are city lots with no overnight prohibition posted, and one is a business that welcomes vans if you buy something. The rule that keeps you out of trouble: arrive late, leave early, and never put out a chair.
