You actually HAD TV stations in North Dakota?
(just teasin!)
Actually, at one time North Dakota had the world's tallest and second tallest TV towers. They had to-- it's so flat there are no hills to put these things on. I don't know if KTHI is still the world's tallest tower (located near Blanchard, N.D.), but I do know the second tallest tower was brought down one foggy morning by an aircraft collision.
