I saw MANY this past Sunday 7/24 going up from Galehead Hut towards South Twin. Talked to about 7 of them making their way up while we were going down and one said about 15 had stayed in the hut the night before. Some started March 2, March 12 and March 20th and said they had about 3-4 weeks left so expected to finish by end of August. When I stopped at the hut, the girl there said there was a real big group of AT thru-hikers that had stayed there on the night before Friday also, so to me it def seemed like height of thru-hiker season since I have never seen so many on one hike like we did that day. Gave them alot of credit too as they all were in great spirits and very friendly and were happy to be in NH.
