The races for Sunday evening at the Pritchard Family Auto Stores Mason City Motor Speedway have been canceled due to rain. The event will not be rescheduled.

“Nearly an inch of rain has fallen this morning and it is still raining, with high temps of 64 and no sun until 4” said USMTS President Todd Staley, who also mages the facility in Mason City, Iowa. “Enjoy your Memorial Day Weekend and remember those who gave their lives to keep us free.”

The USMTS will be back in Mason City for the 11th Annual USMTS North Iowa Nationals on Friday, Saturday and Sunday, July 19-21.

The 25th Annual USMTS Masters takes place Thursday, Friday and Saturday, June 13-15, at the Cedar Lake Speedway in New Richmond, Wis.—another battle in the Collins Brothers Towing USMTS North Region presented by Featherlite for the Summit USMTS National Championship presented by RacinDirt.
