The Books of Magic #40 DC Comics (1994)

 Zatanna, Molly, and Tim are on a road trip. They are driving through very rural Wyoming.

The town they are nearing, Spartanville, also known by some of its inhabitants as New Sparta, was at least partly taken over by a religious cult leader, Absalom Smith, about 14 years previously. Now the town is deserted and run down, and everyone lives in a bunker/fort outside town.
