We are taking a trip back from Indiana after The 500 through southern Kentucky into WV and PA before heading back to Boston. I have our trip pretty well planned through our stop at Cumberland Falls in KY (Thanks Timbo! We're going to be there for a full moon!!).

We have room for one stop between Corbin, KY and Gettysburg, PA and want to stick to our plan of staying off of the interstates until we get to central PA.

What routes do you recommend from southeastern Kentucky through West Virginia into PA?
