I live in eastern ND. Not much to see here except lots of green things growing on very flat land. In Jamestown though there are a couple of white buffalo, albinos I guess, very rare and sacred to Native Americans. So, we built a museum for them.
In western ND the scenery is much better, especially west of the Missouri River. Best thing to see in southwest ND is the Medora musical, in a former ghost town now a touristy trap place. But the musical is a real treat, and the Pitchfork fondue before it is excellent. You know, steaks on a pitchfork, quickly cooked, very tasty that. The show often sells out so you hafta get into town early or book ahead.

There is a campground on the west side of town; I do not know if it is a KOA--check the site above. A wonderful ride through the Teddy Roosevelt National Park starts there also. Buffalo, wild horses, large prairie dog villages, stuff like that. (And now you can carry your firearm through the Park legally, but I'm pretty sure the buffalo are still off limits.)
My younger brother and I will be taking a trip from Fargo to Boise from July 28 to Aug 8. He's a V-Star guy. We're taking Hwy 200 across ND to avoid I-94. It's a wide two lane and cuts across the middle of ND, avoiding the heavy truck traffic on Hwy 2 in the north and I-94 in the south. Medora is on I-94 so you would need to take freeway some of the way. In the southern part of the state Hwy 46 runs across much of the state, but it is very straight. As in so straight that you should practice swerves once or twice a day to keep your steering bearings from seizing.
If you get to the NE part of the state, we have a Minuteman missile silo that has been restored and is open to the public. (The missiles are gone, probably converted to Gen I engines, if the guys on this forum can be believed those bikes go, like, a THOUSAND miles an hour!)
In the middle of the ND is one of the best fishing lakes in the US, Lake Sakakawea. Even better is Devil's Lake in the north central part of the state. West of Devil's Lake on Hwy 2 is the geographical center of North America in Rugby, ND--could be a good photo op.
I am sure there is a lot more, but for a quick visit these are highlights. If you have any specific interests let me know and I'll ask around for you. We have all of 600,000 people here and I probably know someone from every town in the state to ask about things you might want to see or do.
