Illegal as heck here in MN. But many people up North and in remote areas do it. The DNR conducted huge busts during firearms seasons last year and it revealed what a widespread problem it was, I mean still is. One DNR agent cut open the stomach of a guy's deer and corn spilled out of it. When the DNR agent questioned the guy, he replied, that's not from my property. I use whole corn. That's cracked corn. Must be my neighbor.
