Sometmes, I do not get the nickname. If it was applied to Montana, it can make sense (Because they have Glacier National Park and they share it with Canada's Waterton Lakes NP to make it Waterton-Glacier International Peace Park, though the name is "garden".) I would rather recognise North Dakota as either the "Sioux State" or the "Flickertail State."

It's on the wrong border, but if it were on the opposite side of the country, the little urchins would be crying: Turista! Turista!
