Several hundred bracket racers filled the staging lanes at two different races that advertised winner’s purses of $500,000 or more this year. Against the odds, Gage Burch, 19, won the first, the SFG 500 in June, driving a “beater truck” owned by 24-year-old Matt Dadas. Two months later, Dadas reached the final round at the second huge-money race, the Fall Fling 500K, going red by .010. Along the way, the duo and their friends made memories that will outlast the money they made on the racetrack. Más
