I want to spend a few days kayak camping with the main purpose of pro wildlife photography mid-week in Septmember . . . motorboats should be winding down. I know moose, loon, eagles, and osprey are possible at both. Camping free at Flagstaff, Umbagog via reservations. Wind and whitecaps a possible hazard at both. I'm wondering if wildlife opps are stronger at one vs the other, safe overnight parking, etc. Has anyone been to both and can comment?
