One of the things I like to do while traveling is to listen to the local accents, especially of working folk. That said, the once distinctive working class Appalachian accent really has faded away more and more into a generic rural accent similar to what you might hear in small towns in virtually any part of America today.

I think the small town accent is furthered by country music that is largely nationalized these days, the rural identity nowadays more important than being identified by any one specific part of the country today.
