Fargo is the biggest city in North Dakota, and it's one of the happiest in the entire country, too. Like the others on the list, it's ample in natural beauty and culture. Step into the Plains Art Museum, a beautifully updated old warehouse that showcases Native American art. You could also check out all the animals at the Red River Zoo (they have red pandas, guys!), or visit the truly picturesque Hjemkomst Centre, a museum that boasts a Hjemkomst Viking Ship and replica of the Hopperstad Stave Church.
