I like the roads with lots of curves, the more they have the better I like it!! The Dragon has lots of good curves, with a promotion campaign second to none. I don't believe it to be the best road in the Smokeys, but hey they sell a lot of shirts, pins, etc. etc. All the promotion is attracting people from all over, some who really shouldn't be on that technical of a road. I believe the more it attracts, the more dangerous it becomes. If I'm in the area and plan to ride it, then it will be a morning ride during the middle of the week. I've done it several times like that and been mostly alone.
This discussion reminds me of the tire threads. We are all different and have different expectations when we ride. Retirement has allowed me the time to cover most of the really good curvy roads that I've read and/or heard about. Recently, I made the trip to the Hill Country in Texas because I had heard so much about the area. But I was really disappointed, big time!! In my opinion, it does not compare with the good stuff in Arkansas, North Carolina, Tennessee, Virginia, etc. etc.
So, was the Hill Country over-hyped? In my opinion, yes it was! But if you are from Texas and not had the opportunity to get out on some really good twisty roads, then maybe not. It is all relative to our own experience and expectations.
