We paid $35/night with a senior discount.
The park is a grassy field with trees between most of the sites. The sites are back-to-back so you can drive through if both are empty. However, the FHU are in between. Longer rigs may need to pay for two sites.
There is a single bathroom building with a single ample shower for each of the mens/womens bathroom. There is no dump station.
It's first-come-first-served with a self-registration kiosk. There's a nice camp host to come around and verify registration and maintain and water the grass.
