Dr. Horton has done some serious work on this trail...his website
I think Matt Kirk's site will be my go to for quick info.
Things I really like about this route:
Barkley type elevation gain.
Long, (long, long, long) stretches without aid or civilization.
Ideally a SCAR attempt would be good in March, 'cept that is too close to another eveny I'm interested in....
I think I'd maybe like to break this up into 2 sections before attempting the full.
