Stayed one night enroute to Custer, SD. It was a good choice. The young man who showed us the way to our site was extremely helpful and courteous. He reminded me of a 10-year old from the 1950’s who minded his Ps & Qs – a rare find these days. His older sister works in the office.
Gas was a little hard to come by – would recommend a fill-up before arriving if possible. We used their shower facilities and found them far above the norm for most KOAs.
