I was through Millerton last week on my way back from shopping in Canaan. They've got a "trail closed" sign where they're working on the northern extension, but you can certainly see progress if you travel north on 22; look behind NAPA and Four Brothers.
I'm looking forward to seeing how it comes out. We were up in Chatham the other week to pick up a part at the John Deere dealership, and I was surprised how much of the Harlem still exists up there.
"That sapling that once grew just south of Wassaic may be long gone, and the Harlem Line’s appearance may have changed over the years, but for decades to come, I can count on it continuing to provide me with funny recollections"
