Isn't your buck to doe ratio pretty good up there? How about the age structure of the bucks? I have a cottage in Maine, and when you hunt up there, you see maybe 1 or 2 deer a week, but the one you see is almost as likely to be a mature buck as anyting else.
If it's the same near you, I would imagine the only QDM that needs to be done is more food and some coyote hunting.
