Campground near Bllings MT

There are three in the area, one is owned by a forum member, but I'm forgetting which (other then it's not the KOA)

There is another CG in Billings. Can't remember the name offhand but been there a couple of times. Much less than KOA but pefectly doable.

So far in the Billings area, we have only stayed in the KOA (twice). Nice place - a bit overpriced (especially since it's the "flagship" KOA), but for one night, why not. Laundry & bathroom facilities are great. Some of the CG lies along the Yellowstone River, so it's a bit scenic.
