I can understand the inconvenience for the truckers, with the alternative being adding another 100 miles to the trip, but meeting a big rig on the Dragon is a rather interesting experience..
Thank you for posting 
Yeah...um... interesting is one word for it. Happened to us just this past September, it was unbelievable and if it weren't for the highway patrol that luckily for us was "escorting" the rig, it wouldn't have been pretty at all - for myself the wife or the bike.
We were riding into one of the many blind corners when the motor officer instructed us to get around the curve to the pulloff and GET OFF THE ROAD, as we stopped in the pulloff a Semi pulling a large and long flatbed came around the other side of the corner and he needed the entire roadway to navigate the curve..
I't been an ongoing effort for years by many of the local residents who use "the tail" regularly to get the big rigs banned from both the TN and NC side. Unfortunately even with the bans that are in place there are always going to be those drivers who say "awww how bad can it be" and then proceed to find that it is really challenging for them to navigate the road successfully. I wonder if any of them stop at The store for a decal after making it through???
