By the early 1900s, amateur mechanics in North Dakota were building their own motor cars and whizzing down dirt roads at the mind-boggling speed of 8 miles per hour. The other rage of the time was aviation. North Dakotans were in on that, too. In 1910, Archie Hoekse created a sensation with the first successful North Dakota flight at Grand Forks. And there was Frances Klingensmith, the first woman in the state to get a pilot's license.
