No dude, it's shiny side up
Ok, between gatlinburg and Tybee Island (Savannah, for the uninitiated)... what route are you taking?
If you come west a bit, go to Maryville and eat at the Lotus Blossom (think that's right) there near the corner of 321 and 129 bypass. Great Thai. Then you can run down 411, stop at Crockett Creek Beef Jerkey (careful, you'll miss it) and pick up a pound or two of very very good jerky for your trip. A ways down 411 you'll hit 129, which is the DRAGON. tailofthedragon.com . Good way to hop you back over the mountains. Take a camera and a barf bag. 129 will eventually hit 19, which will run through Cherokee on the way back over to I-85. You have now successfully skirted the national park, meaning you haven't broken the law concerning your GUNS. You are taking them, right?
Someone else will have to take it from the NC side, I've run out of knowledge.
