Hey all. Having lived 20 miles from the Dragon in Tennessee, I can tell you don't worry that much about the Dragon for this trip.
The Cherohala Skyway is a fantastic route and to many a better ride. Of course, you have to do the Dragon, but there are so many LEO's there that it's basically become a parking lot. Literally, 9 or 10 officers in 9 miles. Mobile command center and all.
I can show many routes that will be perfect. Route 28 at the junction of 129 (dragon) towards Robbinsville is awesome, then North on 129 to Cherohala Skyway, then towards Maryville, TN, back South on 129 through Dragon.
I'm trying to work out my schedule to attend now.
Above is the best loop I've found on the whole Eastern end of the country.
Hope to help and attend. I have many friends out there that could join us as well, many from the MV Agusta forum (previous bike) and the BMW forums.
