I would like to suggest a great little municipal campground that is really almost a secret. Located in Castlewood SD; 8 sites 60 feet long with 50 amp electricity; water and dump station nearby. $13 per night - reservations can be made (but not necessary) with the city office M-F (closed Wed.) 9-5. It is beautifully maintained, quiet and has a "get away from it all" type feel. We camped here in a Motorhome.
