I'm thinking of doing a section from Sam Gap to just above Erwin (the next road north I think is 395) in July. I'm not much for summer hikes, being from SC I'm used to July temperatures in the 90s. How is the weather around Erwin in July? Miserable hot and muggy, or survivable? Is there decent water through this section, and maybe some streams to swim in if I get too hot? Also, I want to park at Sam Gap and get a shuttle to the other end. Is it safe to leave a car at Sam Gap, and how easy is it to get a shuttle to meet me there and take me north to 395? I've got Awol's Guide and a NatGeo map of this section.
I've never hiked the AT, but I've done the entire foothills trail in NC/SC, and can handle myself for 3 days.
