It looks like you had another great trip. There is so much to see and so many great roads that it's nearly impossible to run out of places to go.
An adventure bike or dual sport really is the best thing for exploring that area however, when I ride my dual sport bikes in that NC I usually end up bringing them up in the truck. You have mentioned on getting a smaller dual sport. Are you planning on riding it down from Ohio?
I ride, Therefore I Am.
