How to read this

Drive times are estimates (straight-line distance +25% at a 55 mph average) to the county center — terrain and traffic will move them. Scores are the national Bolthole Index (see the methodology): a county that tops this list can still rank mid-pack nationally, because proximity to Bay Area is a constraint, not a bonus. The under-2-hour band trades seclusion for reachability; most serious setups land in the 2–4 hour band.
