I am planning on doing my first section hike this Spring and want to do the Smokies. How long would it take, it looks like it is appx 70 miles. Would you go from North to South or South to North? Also it doesn't like there would be any places along the way to re-stock food. Is that correct? I am thinking of starting at Davenport Gap and finishing at Fontana Dam. I have stayed at the resort there and that might be a nice way to end the hike!
