I would like to backpack section 29-31, SOBO, in mid April this year. I am trying to find a good topo map with the trail on it to bring. I plan to do 3 days, 2 nights, with camping about the end of each section. IS there sufficient water for drinking along the route, is there sufficient areas for dispersed camping? Also, I would be coming from Ringgold, have looked at the guidebook, at www.pinhoti.info, for driving directions, which one would i use? Thanks!!!
