Cave City (1983: Doomsday)

Cave City is the base of a group of survivor communities in south-central Kentucky, including Cave City, Glasgow, Mumfordville, Edmonton, Smiths Grove and communities along Nolin Lake and Barren Lake, as well as Mammoth Cave, where many area residents took shelter from radiation in the days and weeks following Doomsday. It is not a country per se, but a loose confederation of towns.
