I visited this campsite over Labor Day weekend. It never filled up, though other people were always there (maybe 1/2-2/3 capacity). No extra/second vehicle fee. There are lots of shady sites, almost all the trees are pines and there's lots of downed, dry wood for campfires. There are two vault toilets, a centrally located water pump (fresh, cold Sandhills groundwater!), and a dumpster. I didn't see any pests like raccoons while there. We heard coyotes both nights. There are plenty of pull offs in the surrounding National Grassland if you want to explore (highly recommend, but wear long pants! Lots of prickly plants there). Overall a fantastic spot for a weekend in the quiet heart of Nebraska.
