You made a blanket statement that 20 deer in a field is too many, without any context. After that you called anybody who wants their deer numbers near capacity irrational and irresponsible. Then, when you got called out on it you decided that you wanted to have a "healthy dialog".
OK. I've hunted whitetails in North Dakota, Montana, Wyoming, Wisconsin, Iowa, Illinois, Missouri, Kansas and Minnesota. I've also driven a motor vehicle while in those states, not sure why that's relevant but I felt I needed to add it. I can say with great confidence stemming from my personal experience that MN manages for and currently has the lowest deer densities of any of those states. I can say that on the 300 acres we own in Kansas we probably have close to 50 DPSM due to the habitat improvements we've made (KSDNR says 30-35). The area surrounding us is 70% ag fields, less habitat than most places in MN. We have no browse line, our deer won't even eat brassicas after 7 years of planting them because there is plenty to eat everywhere else.
The MN DNR has brainwashed the public into believing 20 DPSM is way too many. It's not, for a lot of places with great habitat 50 DPSM isn't too many. They're going to continue spreading that BS with your help, though, and that's why we get a little defensive. Or offensive, depending on your viewpoint.
