BOONE, Iowa (Sept. 4) – Ethan Dotson took the next step toward winning his career first IMCA Speedway Motors Super Nationals fueled by Casey’s championship while Ricky Thornton Jr. took the next toward winning his second of the week Wednesday at Boone Speedway. Dotson, from Bakersfield, Calif., got the best of fellow Shaw Racing Western Region foe Zane DeVilbiss in topping the first Modified qualifier feature. Thornton, meanwhile, led all 25 laps of the second qualifier. The 2016 champion at Boone, he’d started the week by winning Monday’s Deery Brothers Summer Series Late Model main event. Top four finishers from each qualifier advance to the inside row of Saturday’s main event. DeVilbiss, from Farmington, N.M., Corey Dripps of Reinbeck and Jeremy Mills of Britt completed the top four behind Dotson. Tom Berry Jr. of Newburg, N.D., Tim Ward of Harcourt and Jeffrey Abbey of Comanche, Texas, chased Thornton to the checkers. Abbey had qualified for Saturday’s Stock Car main event earlier in the program. He’d won the Southern SportMod crown at Super Nationals in 2016. [Read More]
