HUMBOLDT, Kan. -- Light rain throughout the day Saturday and a forecast for even more at night has forced officials to cancel the second day of the 8th Annual USMTS Spring Fling @ The Bullring at the Humboldt Speedway in Humboldt, Kan.

On Friday, the USMTS Modifieds make their debut at the RPM Speedway in Crandall, Texas. From there, the teams trek to Bayou State with a stop at the Ark-La-Tex Speedway in Vivian on Saturday before wrapping up the three-day stretch at the Boothill Speedway in Greenwood.
