The Lanier National Speedway will host its final race for the foreseeable future Saturday with the 2012 Ice Cold Shriners Bowl, track owner Donnie Clack said. Clack, who has owned the track for nearly 10 years, cited the struggling economy and the lack of financial return on the races as reasons for finally shutting it down for business. “You finally just decide it’s time to shut it down,” Clack said.
