I too am planning a very long ride this summer and will be camping as often as possible. I'm trying to use KOA as often as they exist along the way.
There is a KOA a short way off of the 2 just south east of Minot, Nd.
Right--we also like to stay at KOAs, too, but we'll be staying at Lake Metigoshe State Park up on the Canadian border, its about 70 miles NE of Minot. What we are looking for is something about halfway in between there and Glacier NP. Have looked on the internet for some places to camp, but it doesn't look like there's too much, a few RV parks that just don't look very nice. I was just hoping there was someone out there who has camped somewhere in that area!
