In Minot there are lots of chain restaurants to eat at. I like the new brewpub,
Souris River Brewing. Their beer is drinkable, and they try to source local food ingredients. There's an
air museum near the airport that in summer has some WW2 war birds, and the Scandinavian Heritage Museum has a
replica stave church and a terrifying, 30 foot fiberglass
Dala horse. The two biggest parks are on the river and still recovering from the flood. The only disc golf course is up on North Hill, and is a beast when the wind is blowing, which it usually is. The season is over now, but earlier in the summer you can see musicals at the
Minot State Summer theater.
Of course, between BNSF and CP (or as I still think, Great Northern and the Soo Line), there are lots of trains, a few of which don't carry oil.
If you like to be depressed, there are still hundreds of
zombie homes from the 2011 flood, and there are now actually homeless people sleeping out. Not in the winter, of course.
For Devils Lake and Grand Forks, I got nothing.
