We stayed here this past fall as part of a visit to Springfield, IL to visit family and drive to Iowa.  We have family in Springfield, so haven't ever had a reason to "camp" there, but made this place our first spot.  

It was great.  The owners were super helpful, they literally showed us to our spot (even though this is a big campground) and were available for any questions or needs.

Also - this is right off I-55, so it was very easy in/out with a large 5th wheel, which is always a plus!
