That fish kill at the falls was obscene by today's standards.
One year there was a deer with a malformed set of antlers on Pillsbury Island that would come into the campsites to visit. The staff, (or maybe visitors), were feeding it I suspect. They gave it a name - can't remember right now - maybe Bozo or something like that. Cute little guy. I have seen only a few deer on the Allagash over the years - but you are correct, moose seem to be much more plentiful at least along the waterway.
Yea the house at Locke Dam looks just like it did a few years ago when I was last there.
The motors always bother me a bit. I guess it is one of the compromises they have to make make to keep everyone happy. It does take a bit of the "wildness" out of the trips in the area from my perspective.
