Loud and crowded campsite.  We were butted up on both sides to two RVs with maybe 10 feet on either side.  The campground itself is well maintained, but it's right off I90 with no barrier/trees, and happens to be less than a mile from Sioux Falls regional airport, which also happens to be an Air National Guard base.  Loud.  We used it as a quick stopover which was fine, but I can't imagine spending any time here.
