Would you start in Georgia and head for Maine or vice versa? I'd start in Georgia early Spring.
In Cornwall Ct there is a store right off the trail and I'd cross paths with folks doing the AT. I often shared special treats with them that were very much appreciated. Simple pleasures are huge out on the long trail.

It would depend on how fast i was trying to hike the Trail, Spring in GA = July in New England. Black Flies suck. But if you wait too long then you get snowed on up North. Its a dilemma. Maybe I should just do the Columbia Crest trail:)
