to my knowledge, most all of the core of engineers land along the rivers is open to hunting. I did quite a bit of hunting in IL in those locations in years past. Also, some of the parks have sections open to daily sign in hunting for non-res. I've gotten into some really good hunting on a couple of those, too, so long as you are willing to go a smidge deeper than the locals. The catch is that a significant portion of their parks lands is either a draw or open to residents only, though. So, be sure to check that.
