I will second all of the advice here.
We used some of Journeyman's recommendations around Franklin while we enjoyed some of the worst
July weather NC had to offer (as mentioned the mountains got a good soaking last year).
BRP was hit or miss for us, rain / fog and 50F we had it to ourselves.
We tried a chunk when coming back north, but weekend traffic was no fun.
I expected the Dragon to be over rated, but even with all the amazing roads, that was a blast.
Keep your shit dry and have safe trip.
