On a recent street ride we rode this wonderful little route until it went unpaved.
I explored this road with Milner back in 2014. If memory serves it's moderately intense with some interesting water crossing. It's not something one could take a car through. I'll have to go back and refresh my memory.
Recommended to Duncan to check out. OSM lists this road as unpaved. I think I remember it from the Shenendoah 500. There are quite a number of very good unpaved roads all through this area.
OSM lists this as unpaved. We'll check it out.
