What's it cost per night? Do they have primitive sites? Like for a tent?

It's not very expensive. We paid $ 57 per night for our 29 feet during the week of the biker rally in Sturgis. They also have tent sites.

Also, their sites are pretty close together, but it's a nice campground. We'd stay again. Inexpensive.

Yes they have tents sites. They are not expensive. Kemp's is a nice camp. Call them for rates or go online
