I have met a ton of duck hunters at the Bay in the past several years (All exceptionally nice people. . . even the wardens!) so it is quite possible we have met OR at least been at the landing at the same time!
I am usually pretty easy to identify I am the guy with the crowd around him as he assembles his Porta boat! :) Used to launch a lot from the warden camp but now tend to launch more often at the Bowdoinham launch. These days I typically set-up "around" center point or brick island.
Whoever had those Goose decoys set-up on the edge of the grass down toward the Androscoggin river this year must have done a ton of early season blasting?!?! That appeared to be a really nice set-up.
Drop a post as to how you hunt the bay and any possible danger spots, how you deal with the thick fog, decoy spreads, etc., etc. I am always willing to learn from someone with much more experience than I.
P.S. Forgot to answer your question on the changes? Did you mean number of ducks, number of hunters, hunter attitudes, etc? I do have to say that I was a little unhappy with the number of cripples that I had float by me this year. Must have seen almost a dozen teal and mallards. . .wanted to pick them, but that would have put us over our limits. Hadn't seen that in recent years so I wonder if a lot of people were sky busting?
