The engines are still warm and the dust has barely settled from a wild weekend of racing for the Summit USMTS National Championship presented by RacinDirt at the Ogilvie Raceway, but there's no rest for the wicked this week.

The best of the best in dirt modified racing travel three hours south on I-35 to North Iowa's Action Track for a back-to-back tripleheader at the popular Pritchard Family Auto Stores Mason City Motor Speedway in Mason City, Iowa.

The three-night excursion happens this Thursday, Friday and Saturday, July 20-22, for the 10th Annual USMTS North Iowa Nationals presented by Christie Door Store—a prelude to the 25th Anniversary USMTS Silver Jubilee here in August.

The winner on Thursday gets $3,000 while Friday's feature winner takes home $5,000. Saturday's curtain-closer will dole out a whopping $10,000 to the USMTS main event victor.

After a runner-up finish in Saturday's Mod Wars finale, series points leader Rodney Sanders leads a charge of throttle-mashing contenders into the 1/3-mile speedplant as the seeks his fifth USMTS title.
