Minneapolis and St. Paul are not real cities, but rather are giant towns which are essentially puppets of the suburbs, who prefer to appear to the world as "Minneapolis". Well, if the Mexico City area was as much composed as Minneapolis of what are in fact suburbs, it would be BIGGER THAN CALIFORNIA AND NEW YORK COMBINED! So who now can claim that Minnesota isn't suburbanite dominated?
Granted, there are a few true cities in Minnesota as well. There's Rochester for one, home of the world famous Mayo Clinic. Virtually no suburbs involved there! Good place for sick rich people to get chemo and die, I suppose!
Another more city-like region is Duluth-Superior (MN/WI). When there it's interesting to speculate how things would be if Minnesota wasn't so cold in the winter. Most likely Duluth would be larger than Minneapolis-St. Paul and would be world-renowned, like comparing San Francisco with Detroit. But since it's so cold here, mere physical reality has led to a rather isolated hick society in northern Minnesota which has developed its own unique patterns of urban development but which has at least maintained some dignity by maintaining its distance from the jerkwater major metro area.
