My tattered Nov. 1951 Hop Up magazine has 17 pages on that year's Bonneville Nationals . A young Mickey Thompson got the Hop Up thrashing award for dealing with lots of problems and getting top time in class with his 35 3 window . Photo of Ray Brown topping off his roadster tire with a hand pump . It said lots of racers slept in sleeping bags on the hanger floor because they couldn't get rooms in town .
