Race fans will have their choice of either two wheels or four wheels on the weekend of June 13th-15th at the Knoxville Raceway. The World of Outlaws will make their only stop in Knoxville before the Knoxville Nationals that weekend, and after a year away, the A-M-A Flat Track Motorcycles will also race. General Manager Brian Stickel tells KNIA/KRLS Sports fans can come out to see both for a discounted adult ticket. The schedule for that weekend will be Vintage Flat Track Motorcycle on June 13th with the sprint car races on the 14th and the A-M-A Flat Track Grand Nationals on the 14th.
