Spent three days there in early September. 18 sites, water available but no other services. Half were drive through that easily fit our 36 foot A class. Trees so had some shade that helped keep things cool. Reasonably clean and tidy, garbage cans were emptied. Short walk to day use and the Yellowstone river. Right on the edge of town and as is the case all along the I90 & I94, there are trains.
We'd definitely stay again.
