If you are looking to bring the boat and catch lots of salmon then Maine would seem like a good bet. Plenty of lakes with a great population of Landlocked salmon.
Syracuse area in New York is a good bet for the salmon that run all the Lake Ontario tribs.
You should specify a little more as to tackle that you would like to use, time you are able to travel,, costs,, etc.

"Well, this is called patience by those who don't know. But it is nothing at all like patience. It is hope, undying, unquenchable, the heart and soul of salmon fishing".
