In my opinion the Dragon is overrated and dangerous at times due to the idiots coming the opposite direction who come over the center line on blind curves. The Cherohola is beautiful, not challenging at all. The scenic views on the Blue Ridge Parkway make for a great ride, but the 45 mph speed limit and heavy enforcement is a pain. As others have said, the roads in that part of the country are great for riding. Another great area if you get to it is southeast Ohio around Athens.
