I will post what I am up to. The Bigelows are my favorite range in ME, too. I did the traverse last summer as well I am not much of a kayaker but I can see how great it would be on Flagstaff. I am doing small segments for now. I am just going from the Baldpates in Grafton notch to east b hill road in 2 weeks. it is a test run with a friend who has not backpacked in a while. Will stay at the Frye Notch Lean-to overnight. I ma trying to do sections I have not hiked before.
