Any "old-timers" out there who can answer this question: Has the AT route changed much thru NC/Tenn in the past 20 years? Reason I ask, is that I was given a trail map for these states, dated 1981. If the route is basically the same now, I can save a few bucks when I purchase my maps for my "almost" 2004 thru-hike (another story). I realize that many thrus don't see the need for maps, but I take them along as a "security blanket"; also gives me an idea of the elevation changes I can expect with each day's hike. I know that the shelter info on the old maps is outdated, but I'll be carrying a Thru Hiker Companion for that info.
