Yes indeed... very hot, very humid. Frankly I'd be pretty uncomfortable there in July. Consider sooner! Or later! Lots of bears, that could be fun. It's been a while but I recall being very impressed by the Smokies near
Asheville NC.
I drive through WVa regularly and there are many times I've thought of exploring a bit but haven't gotten to it. Idid have a good time at the Blenko glass factory recently, that would be an interesting spot for occupational photography and abstract macros (as would the nearby coal mines). There are also some good scenic rails spots in WVa, I've heard.
Shenandoah, now that's up in my neck o' the woods....
P.S. Isn't there a spectacular Carnegie mansion somewhere along the blue ridge parkway? I cannot remember the name for the life of me, but possibly a very nice destination.
