What is Limehouse, SC?

In "The Story of a Dead Man" Limehouse, SC, is the small town between Atlanta, GA, and Charleston, SC, where Billy Renfro claims to have lost his left eye fighting a redneck. Billy stops at the general store to buy an orange soda, but the white supremacist owner refuses him service and Billy draws his .22 too slowly. Billy must withdraw and drive away to the sounds of gunfire and rebel yells. Returning from his successful repossession mission, Billy again thirsts for an orange soda, slips in unnoticed, holds his .22 ready at the counter, and this time he fires off shots and gives a swamp cry as he heads for Atlanta.
