Sweet pics! I added the little camera icon to your post since it has embedded images, that's our clue for people on slow connections.
I've done a lot of segments of the AT and someday it will bubble up my priority list to finish the gaps. Hiking in the White Mountains often means walking on white blazes to begin with, and I also did a number of my 4000-footers with a dedicated section hiker.
Some of my major sections in NH:
- From Kinsman Notch (Rte 112) over the Kinsmans, down under I-93, up Liberty Spring, and across Franconia Ridge to Lafayette.
- From Mt. Guyot out through Zealand Notch and down past Ethan Pond to Rte 302.
- From the summit of Pierce to the summit of Washington.
- From the summit of Adams over Madison, down Osgood, back to Pinkham, across the street and up Wildcat, over the Carters and Moriah, and down Rattlesnake to Rte 2.
- The Mahoosuc Range from Mt Success to Old Speck.
Also, in Maine many of the 4Ks are along the AT as well as the AT being just incredibly gorgeous hiking up there. I've done the full stretch from Rte 4 over Saddleback and the Horn, side-tripped to Abraham, Spaulding, Sugarloaf and Redington, over the Crockers, across Rte 26, over the Bigelows and Little Bigelow to Long Pond Dam Road.
And in VT a stretch of the LT/AT from Little Killington up to Rte 4.
The only aspect of the AT that I avoid is backpacking when the Thru Hikers are expected to come through, because it gets too crowded. Conversely, though, I've always wanted to provide trail magic and hope this year to do something special in that regard.
