Within 2 hours of Chicago is tough, unless you mean 2 hours from the edge of Chicagoland, as it takes close to an hour to get out of down town. I think the closst areas where you are going to find leasable property is in the Illinois River valley (Bureau County maybe), which is probably over 2. There's a website that pairs landowners with hunters:
http://accessil.org/ . I don't know if it's any good. I am primarily a public land hunter, and it's okay. You might want to consider southern Wisconsin as well (way more public land, but not sure about leasing). Good Luck.
