The wife and I just relocated to Kentucky, and we haven't had the chance to ride many of the roads you mentioned....
Have you ridden the area around Cave Run Lake and Red River Gorge (including the Nada Tunnel)??? We've been impressed w that part of the state and have come across several waterfalls too....

Dont know those places. The post I made was for a guy near me to ride to Maggie Valley from Ohio
