To bad you northerners couldn't hunt all the cemeteries up north of I-80. My in laws live in Lombard and when we make the journey north I always see deer all over the place feeding in the cemeteries and in all those preserves.
I would consider planning a few hunting trips to central and southern IL to some of the state parks around here. While they also have alot of hunters there is still a lot of land and you can scout out a good spot away from others.
