My father told me about "Raintree County" and "The Kentuckian". "Raintree County" was filmed around the Danville area. "The Kentuckian" was mostly filmed around the Owensboro area with some video produced at the Falls and around Levi Jackson State Park, using lots of locals as extras.
The only one that I have actually saw was the flyover in "The Fire Down Below".
I only added this to see if it would get copied to another site.
