In "Freedom Bus", Forrest Bedford is referred to as a new U.S. Attorney "in the Fifth District", presumably a reference to the Fifth Judicial Circuit of the federal court system. In the late 1950s and early 1960s, the Fifth Circuit included Alabama, Florida, Louisiana, Mississippi, Texas, and Georgia (along with the Panama Canal Zone). Since the first five states can each be eliminated based upon statements made by characters throughout the series, the most likely setting for the series is Georgia.
