We use to live in Ohio. West Virginia was nearby, it and the rest of Ohio south of Cleveland was known as Hillbilly country. We moved to North Carolina twenty plus years ago and learned about Red Necks. We are close to Florida and hence, have become familiar with the term, Crackers.
Upon awakening yesterday morning, my dear wife Lee turned to me and said without further introduction: "Do you know the difference between Hillbillies, Red-Necks, and Crackers?"
Barely awake, I said, "No, what?"
"Terrain!," says Lee.
