The 16 day season structure will "typically" add only 2 days to a hunters time in the woods. This will in most likely not dramatically increase the deer harvest for the next few seasons, as the EAB seasons have seen to that.
The most opposition I have seen is from BOWHUNTERS. Mostly due to the other factors that go along with the 16 day season. Such as the 1wk (in OCT.) Youth hunt as well as the earlier muzzel loader season, supposedly to be held during the same week as the Youth hunt.
Now for a group who has a roughly 120 day season, currently broken up only by the 4 day oct. t-zone, 2 day youth hunt, 9 day regular firearm, 4 day dec. t-zone, and dec. muzzel loader seasons, they sound awful selfish to me.
The over-all population goals are what (IMO) is driving the decision by the DNR to continue to offer and expect the increased harvest of doe's. What this does is lower the number of hunters in the woods, because they aren't seeing anything, as they had in the past.
