From a Wikipedia entry for 'Petticoat Junction':
Trips on the Cannonball usually include a stop in Hooterville ("Elev. 1427") at Drucker's Store, run by Sam Drucker (Frank Cady). Drucker's is the local hub, where menfolk come to play checkers and chat. Sam Drucker is the postmaster, editor of the newspaper, Justice of the Peace, county clerk, water commissioner, marshal, deputy sheriff and occasionally the mayor. His telephone is a lifeline for the Bradleys, Uncle Joe, and others. The fictional Hooterville became the main town for Green Acres in which Sam Drucker still ran Drucker's Store. Pixley was apparently the county seat although a nearby community was "Bugtussle," the original home of Jed Clampett and his family from The Beverly Hillbillies.
