Chicago location

The airport is KARR, if your an AOPA member, look it up on their website. Otherwise, it's about 50 miles from Downtown. It's a class D airport and isn't too busy. 3 runways, main one being 09-27 and then 18-36 and 15-33(?) I believe. Overall nice airport, you only have to fly for like 5 minutes to get to an area to do the maneuvers and most of the landing practice was at DeKalb with the instrument approaches at KARR.
