I live near the AT in Georgia, and I have hiked this section many times. I know of a Cooper Gap on the AT near Blood Mountain, where Meredith was taken. (But for all I know, there may be a Cooper Gap in Pennsylvania!) Down here, the sequence goes like this: Cooper Gap, Gooch Gap, Woody Gap, Jarrad Gap, Freeman Bird Trail WSW trailhead, Slaughter Gap, Blood Mtn summit, Mountain Crossings Store at Walasi-yi (Neel's Gap), and, altogether, this represents, if memory serves, about 25 miles.
I tried to read all the posts, but I may have missed something. You may already have this article from the Gainesville Times in north Georgia, which discusses how Hilton's presence on the AT, at Gooch Gap especially, was known to LE for the past nine months!

In case I got the url messed up, the article discusses how hikers complained of Hilton "taking over" the Gooch Gap shelter, spreading his stuff around, running them out when the through-hikers tried to stay there, and so forth.
To me it's a mystery why LE didn't hide out and lay some binocs on him in order to roll him up for "disorderly conduct" and toss his van. I thought if you were an ex-con, LE doesn't need a search warrant. Does any one know about this? If Luminol had turned something up in that van, Meredith would still be with us, maybe!...Unbelievably sad!
I'm thinking of heading up there this weekend to see if any the coves around Gooch Gap shelter have anything unpleasant buried in the leaves. If LE didn't bestir themselves for nine months prior to Meredith's tragedy, I wonder how much, really, they've bestirred themselves since.
By the way, did anyone hear a story about a "store clerk" seeing Hilton walking behind Meredith "near the trailhead" with his baton in hand? I have that in my notes, but missing the attribution. I wouldn't have thought the store would be open on New Year's Day. Have to check on that because the trail to Reece Loop, where her car was parked, is at the end of a different trail from the one that leads to Mountain Crossings Store at Walasi-yi. If she was seen walking to the store, it may have meant that, suddenly, finally, she'd gotten scared and was obeying martial arts rule number one: get to a public place if you can.
