I wouldn't be for a 1 buck rule. My reasons are simple. If a bowhunter or muzzleload hunter harvested a buck in the early season. Then didn't recieve a DMP tag, his season would be over come Reg. seasons. He'd be done hunting until late season.
Presently a hunter canharvest a buck in early season, and another during Reg. season. Many hunters travel throughout the state & hunt different WMU's., and other woods. The only way a hunter can take 3 bucks during a yr season is if they have a leftover Reg. season tag from the previous yr. , and hunt the last 4 days of Sept. in the Northern tier with a bow.
The only thing I might be for is a hunter can take only 1 buck in a WMU. His 2nd buck has to be harvested in another WMU.
