Beat, kick stab do what you have must to make yourself feel good but the horse is far from dead.
The "brown seasons" do effect deer harvest. You can't shoot what you can't see. And most hunters can't see deer as well or often with limited snow cover. The reason the harvest was as high as it was in 1990 was because the population was high going into the season. I'd be quessing but I'll bet the kill was a smaller percentage of the herd size than the DNR wanted havested.
Further, the brown season effect does not effect the state equally. There are times that everything north of Hy 8 has a good snow cover and the remaining part,the greater percentage of land, has no snow cover. Agian this is looking at the entire picture not just what you a single but deeply concern individual can see from the limited position.

Man thats some really large font you used there TJD.
