The movie "Deliverance" was set in Georgia. Georgia is a state in the southern U.S. While a tiny portion of Georgia is included in the region commonly called "Appalachia", the vast majority of the state is located outside this region and shares little to no cultural traits with the rest of Appalachia.
Based upon this information, which has heretofore obviously escaped your legendary powers of fact-finding, please refrain from referencing the movie "Deliverance" or its main musical theme "Dueling Banjos" in your stories about Appalachian voters. We're asking politely. For now.
