robermv32 ; I saw an article recently about that very issue. It said that 18 wheelers are now banned. Can't remember what website I saw it on. I'll try to find it and post a link.
Chek this out. A little info bout NC banning trucks. Tail of the Dragon at Deals Gap, motorcycle and sport car two lane tourism serving Tail of the Dragon at Deals Gap, Cherohala Skyway, Moonshiner28, Devils Triangle, and Six Gap North Georgia.
