August 30: Cadillac Endurance Test
W. H. Horton, owner of the Horton Motor Co., sold Cadillacs at his dealerships in Devils Lake and Fargo, distributing the cars all across the state and into eastern Montana. He was such a believer in the superiority of Cadillacs that he made an unusual offer in the spring of 1913. Horton challenged any owner or dealer of six-cylinder cars to race him from Fargo to Minot and back, with the winner getting $100. Horton would drive a four-cylinder stock Cadillac.
