I was just looking for this area on a map of western Nc and eastern Tn.
Noticed that not only is there US129, but using US74 on the SE end of
the Dragon, you can go north a short ways and pick up 28 to come back
to the Dragon on the NW end. 28, it self, looks to be nearly as twisty
as is US129. In fact, this seems to make a rather nice loop that could be
traveled rally style for time. That is, if I'm looking at the right section of
US129.
