Roy Rogers was a Bonneville racer! 107 mph

Not sure why Roy is with the trophy given to the Shadoff Special but here's the history of it http://www.ugofadini.com/shadoffstory.html , and the Maremont trophy ( comes with a 1000 dollars ) given to the racecar with the best design and construction (engineering excellence).

The Shadoff Special was designed by Dean Batchelor
