KNOXVILLE, Iowa – Heavy showers and a bit of hail during 410 time trials was too much for the Knoxville Raceway to take Saturday night during Slideways Karting Center/Knoxville Hospital & Clinics Night.
The wet grounds caused a cancellation of racing.
Racing resumes at the black-dirt half-mile oval on Saturday, June 1 with McKay Group/West Bend Insurance Night.
