If I were you I woudl stay on the IA side. Anytime that you want to go to IL to hunt you can draw a tag as they never run out anymore (except for maybe 1 or 2 counties). You should have no problems coming over to the IL side of the river there and hunting Knox, Warren, McDonough. The cost is cheaper to come and hunt IL out of state also. The drive from Burlington to Monmouth isn't to bad, it was part of my jaunt over to our farm from Iowa City to Galesburg area. You should be able to do it in under 40 minutes.
