Nice ride, but be careful. GPS is sending 18 wheelers across the mountain on 129, even though it's posted "No trucks / Semi-trailers". Last couple of times I've been across have been a nightmare, waiting on wreckers to drag trailers around the curves.
Another nice ride in that same area, if you don't mind gravel, in Tatum Gap ( look up the 'Gravel Dragon') road from Robbinsville across the mountain to Andrew's, N.C.
