I havn't seen anyone else mention this. Tortilla Flat has developed an overflow parking lot just southeast of town. Hikers can use this lot. Follow the stone road to the right on the east side of town by the museum. At the rear of the lot, by an unmarked trailhead you can use to go to Peters Cave, there is a sign asking you to fill out a permit for overnight parking so they don't bother or tow your car. No charge-just place it on your dash so they know its not abandoned. A nice jesture.
Its private property, not subject to ticket by the forest police
