I didn't realize that was the weekend for the RS festival. Let me re-think my directions. Take alt 58 w to St Paul and then take Rt 63 to McClure. Again, not really the best roads around, but that will be the quickest for you and tractor trailer coal trucks use these roads each and every day. You will probably pass several on your way. Just so you know.
This area has a plethora of music venues and that just begins "the season". If you have more time, you should plan to hang around for a few more days and take in the Country Cabin,
Appalachian Traditions, the
Carter Fold and the
RS Museum There are many, many more and you can get old-time music almost every day/evening of the week.
