As the book rolls along, the indicator on the speedometer goes steadily up. Art Arfons managed to obtain the world's lend-speed record When he drove a run averaging 536.71 mph at the Bonneville Salt Flats in 1964. Just as startling is the fact that the car Arfons drove was a small, outlandish-looking, low-budget affair, which he designed and fashioned pretty much by himself from second-hand junk. The book follows Arfons from his first drag-racing to a long description of Arfons' final session at Bonneville. For readers interested in more than the mere numerical fact Of speed, the descriptions of the way Arfons' various ""Green Monsters"" were constructed and of his driving methods are minimal. And the insertion of ""human interest"" (e.g. Arfons calling up worried wife June before and after every race) is dreary.
