Have stayed at both the North and South units often while visiting family in the area. Prefer the North, less crowded. No hook ups, cell service, or TV unless you have sat dish. There are water and dump stations, not always open. Gets hot in summer and early fall. North unit has Bison, longhorn cattle (last herd around), big horn sheep, pronghorn, deer, coyote, turkeys, etc. South has wild horses and lots of prairie dog villages also.
