Many years ago, before the DNR decided to take control and manage the herd, in Wisconsin we used to have some fields where you would see twenty deer at a time. Some farmers claimed even more then 20 at a time. All of that is about gone now. The DNR claims all the deer together like that is what caused the spread of Chronic Wasting Disease. This could well be, but it was sure nice to have a deer season where you were almost certain that if you hunted hard, you would take meat home.
In that field, that is a lot of deer moving. This of what a herd like that would do to a cash crop of say corn or soybeans.
