Hmm, why would the Vikings be most hated in North and South Dakota? The border Minnesota and to the South and East are Nebraska and Iowa, who don't have pro teams. Speaking as a former Iowa resident, there is a hodge podge of fandom there. You can find fans of the Chiefs, Vikings, Bears, Packers and even some St. Louis there. I would think North and South Dakota would be squarely in the Vikings camp, perhaps some Broncos fans in the West.
