After reading numerous posts recommending ATC maps over Nat Geo maps for the Appalachian Trail, I am looking for a place to buy the ATC maps. The places I have found, Appalachian Trail Conservancy, Outdoor.org and Amazon all say they have the ATC maps, but then show the Nat Geo map and reference it in their description. I guess I am looking in the wrong place. Can someone point me in the right direction?
