I hiked about a 50-60 mile section a few years back. Started at the Nantahala Outdoor Center on HWY 19 in NC and ended on the Lookout Mountain Senic HWY in GA (76). Took about 5.5 days. I loved it though. It was mid summer and quite warm on the startout but at the end we had a bad thunderstorm and cold front which brought about some hail and about a 40° temp. You guys will enjoy it for sure.
