The Cobb County web site says No overnight parking.
Most folks leave their cars at the Publix Shopping Center at -1.5 miles up hill from Mavel Parking lot (MP 0).
Another alternative near MP 21 Tara Drummond P Lot, across the four lane (US278) on a bike trail to the Paulding County Government Complex you can overnight there, lighted Parking lot, with PC Sheriff patrols, and Park facility (bathroom).
