I also live in Wisc. Southern Wisconsin where we had earn a buck and at first I wasn't fond of it, but in the second year I began to see bigger bucks as result of it.So I actually like it.Last year they had earn a buck during certain periods and no earn a buck at other times which just was more confusing. I hope this year they resort to earn a buck for the whole season and allow no bucks to be taken in the four day October gun season.
The problem with earn a buck was people would take a road killed doe into register it as a bow kill for the buck tag. And registration stations would allow a doe to be registered numerous times by different hunters to each get a buck tag. This I have no proof of, but heard the stories. BUT, what I do know is that I killed a doe, took it to a registration station which happened to be a bar, I filled out the paperwork inside, they handed me the tag and I was off. Not once did anyone see the deer and I could have very well registered the deer once more or give it to a buddy to register for his buck tag. But I didn't.
