Those associated with the Auto Trader Southern Iowa SprintWeek extend their sincere condolences to the family and friends of Keith Hutton, who tragically lost his life last night at Oskaloosa. Keith was a Queensland, Australia, native and speedcar (midget car) racer who relocated to Knoxville, Iowa, with his wife Jenny to follow their dreams in open-wheel racing. The always-smiling Hutton finished third in this year's Hoosier Tire Midwest Masters Classic 360-cubic-inch sprint car race at Knoxville, behind winner Jimmy Sills and runner-up Roger Rager. Rest In Peace, Keith.
