Yes this race has been cancelled.

ZTR Speedway has its own insurance . This is not an USLMRA sanctioned event . There is NO USLMRA Membership fee required.They run USLMRA rules for the sake of being compliant with us , being Kansas , Iowa , and Illinois. Jake runs Karts , Quads and has pulling events so he went another way with his insurance. So this race is open to all of us but you must pass US tech ESPECIALLY Billet Flywheel!Exceptions being GP classes and they must meet RPM rules. Any questions? Please comment Thank you Marty
