In Itchyville, with no paved roads, a big box store is actually a big box made into a store. A grocery (jerky and beer), Laundromat & bait (jerky and beer) store, with some old John Deere paint in the back. Carl will have to go to the "Big City" sooner or later. He can't order online because of what happened to the last UPS guy. Ever see "Deliverance"?
Don't forget pickled eggs, cracklins, and a shotgun for smart alecky Western yankees.
