THen check with your semi community about that road. I know of NONE Of us who trailer thru the Dragon. If you come in near mid-day, you may be fine. If you come in around 5-7pm, sucks to be you OR to be anyone who meets you in a curve.
If you are over the line, you are liable for anything that happens (and you WILL be over the line about 150 times in 11 miles).

Herei is what I'd do: Set GPS for Tellico Plains. Once there, set it for RObbinsville, NC. Once there, enter lodge address. Given you will travel the Dragon at 15mph, and my route you will average 45-50, I don't think the time difference is going to to be two hours, maybe an hour - but you won't be as stressed and your accident risk is about 1/250th this way. Do not leave Tellico PLains expecting gas in the next 56 miles!

We look forward to yet another first timer, you will NOT regret this weekend, but if you show up Friday night and leave Sunday morning you may ask yourself why you even bothered. Try to get there Thursday - it's way worth it.
