I will be going to Alaska next month and that leaves only 1 state left that I haven't seen. I'm having difficulty in finding things to see and do in North Dakota. I usually devote 10-14 days to really explore a state. I need to find some interesting places to justify the cost of the flight. I love history, architecture, natural wonders, historic homes, etc. I'm not into night clubs, zip lining, amusement parks, spas or shopping. Can anyone make some suggestions?
