The fairgrounds in updating their facilities. There is now a small private full hookup campground just inside Gate 6 enter from Lincoln. The new campground also has a new restroom. The remainder of the fairgrounds is a series of "campgrounds". Most with electric only. Electric is steady. Plenty of shade. The restrooms in the older areas are tired. Reasonably clean but tired. Rain will muddy some of the roads. Takes a day or two to dry out. Saturday is race day at the race track on the North end of the fairgrounds. If you are into dirt track racing it's cool. If not it will be noisy for a few hours. And there is a DQ just outside the fairgrounds. We camped at South Dakota State Fairgrounds in a Travel Trailer.
The place is huge and wasn't full, so we were allowed to park where we wanted and face whatever direction we preferred. Like others, we took up several spaces, but were charged for one. Most campers were very spread out or in small groups. It was quiet at night except for three train whistles. Security fence. Grass sites, some have shade. Gravel and paved interior roads. Dump station nearest us was clean, but wouldn't accommodate a large RV as access was tight and there was a gravel ramp on either end. It looked very clean. Showers/bathrooms were dirty with wet concrete floors. We use our RV bathroom and shower, so it wasn't an issue. A few sites have water and sewer hookups. With a motorhome, stick to the roads on the east side. Some of the driveways and crossroads in the middle and west had a dip that would have dragged our undercarriage. We cleared tree branches and overhead wires, but we were watching closely. Not a bad place to overnight if you use your own toilet and shower.
