This was a very nice park and due to the location (you could easily see Crazy Horse Monument and you were overlooking a pretty valley and were next to the Michaelson hiking and biking trail which is hard packed and runs for many miles). Owners' are nice and the place is clean and sights have some shade. If you need WIFI you can drive 2 miles to Custer, SD and sit out side their library and use WIFI. If open go inside. Less than a mile from Crazy Horse. If they had WIFI and TV I would give them a 10. Actually we could pickup 4 channels including CBS.
The park sites were extremely close (3-4' apart). We had reservations for 5 days with full hookups. When we got there the owner said that "full hookups" to them meant the "honey truck" would come to your sight twice weekly and drain your black water. With the gray water we were told to drain the gray water on to the ground. This is very unsanitary. Due to a power failure on and off all night we left the next day. We made reservations 30 days in advance and received a horrible RV spot. The park was clean, but you were crammed in.
