I am a life long resident of ND. Where do I start. Well the west has the Badlands (best seen late May early June very pretty land) easy access to the south unit of Theodore Roosvelt Park but the north unit up Highway 85 is more scenic). Bismarck is our capital and situate on the Missouri River, it has several attractions, the State Capital (know as the sky scraper on the praire), the heritage center (North Dakota history) and Fort Abraham Lincoln (the fort Custer stayed at before the battle of Little Big Horn). As you head east you will realize the land changes and before you know it you are in the Red River Valley a area where in place the elevation doesn't change more then a foot in 60 miles. On the eastern edge there is the largest town of Fargo (180,000).
Depending on your wants ND can probably provide.
Camping is available all over
Fargo, Bismarck, Grand Forks and Minot all provide for arts and entertainment.
Hunting and Fishing is abundant
the air is clean and the sky at sun set is gorgeous
