Yes, open season all year long tends to thin the herd a bit.
Funny you would say that, they have been doing the 'open season all year long' for say at least 10,000 years. I think you've been taken in by an urban myth. No doubt that environmental issues [wolves & habitat destruction] have had far more impact on game herds than hunting, and up here it's not unusual for trains to kill more than the annual allowable harvest [for all hunters]of moose.
IF what your after is untouched wilderness hunting, you have to look for no road access, no major rivers that hunters can travel by jet boats, no railway tracks, and no power or pipeline right of ways. [very limited access]
