Southern Iowa Sprintweek shifts to the Southern Iowa Speedway in Oskaloosa for two big nights tonight and tomorrow. Tonight is the annual Front Row Challenge which will feature the 410 winged sprint cars in action. Many of your local favorites, plus several World of Outlaw drivers including Donny Schatz, Joey Saldana, Paul McMahan and more will be competing. The driver that earns the pole position will have the option to start there and earn $10,000 with a win, or give up that front spot and earn $50,000 if they can win from the back. Tomorrow the wings come off for the Ultimate Non Wing Challenge featuring the best non wing drivers from around the country. Infield party pass or grandstand tickets are available for both nights by calling McTwo Promotions at 515-957-0020.
