This is a no-nonsense, FHU RV park, not for long-term, really. It obviously makes its money during Sturgis M/C Rally in early August (a week long party). Rest assured that everything in the Black Hills is booked for that week. If you're not participating in the Rally that weekend, I recommend any other part of the country. 

There is a LOT of tent capacity, and about 40 RV sites. Sites are well-maintained, level, power and water is good, sewer hookups work properly. Laundry is well-cared-for, and clean. Showers are good, Bathrooms are with the showers. No Wifi streaming, Verizon is pretty slow, but acceptable. All RV sites are pull-thru and well-spaced. 

Cash only for Passport America, also accepts Good Sam and military veteran discounts. 

The owner is no-nonsense, but thoroughly likeable, and very flexible. Highway noise is not a problem most of the night, and we weren't bothered by rail noise all night (which is rare in the West). 

Park of gravel/grass mix, no real shade, but these are grasslands at the foot of the Black Hills, so almost no dust and dirt. Road in is well-upkept, but dirt. Do NOT wash your rig - water is scarce in these parts. 

We paid $23/night Passport America for three nights, and $45 for another (military). Otherwise, this is marginally affordable for us.
