Real bruisers can be found through out the entire state. How ever I do agree that chasing them in the North woods is by far the most gratifying deer hunt for me. I have hunted the Western Mountains above the Rangley / Eustis area for the past 15 years and would not hesitate to recommend that area. How ever most of Northern Maine offers remote hunting with low deer density and little hunting pressure with the chance at true trophy. Where ever you chose you most likely will hunt hard for your opportunities but you will not see hunter orange behind every tree either.
Good luck
