There’s an important distinction to be made between rednecks and hillbillies. The south would like you toe believe that anything non-urban is redneck, this is not so.
I would suggest Shenandoah National Park. Partly for the beauty of the park itself, and partly because the drive from Indiana will go through some gorgeous terrain. I would suggest taking route 33 through Wayne National forest in Ohio. You can stop in Athens as a halfway point, it’s a picturesque little college town nestled in the hills.https://lemmy.world/pictrs/image/eca18718-ceab-4a32-a505-877aac0bb4ed.jpeg
