HUMBOLDT, Kan. — The race scheduled for Friday, March 14, at the U.S. 36 Raceway in Osborn, Mo., has been canceled due to inclement weather hampering track preparation. The rugged road warriors of the O’Reilly USMTS National Tour now set their sights on Saturday and Sunday, March 15-16, to kick off an exciting 2008 campaign for America's Hottest Ticket on Dirt.

SATURDAY, MARCH 15 - HUMBOLDT SPEEDWAY, HUMBOLDT, KS

The Humboldt (Kan.) Speedway will host the “3rd Annual Havoc at The Hummer” on Saturday, March 15. Defending USMTS National Champion Jason Krohn is the defending race winner at Ron and Rhenda Whitworth's speedy 1/4-mile oval, and will be looking to repeat in the first race of the Mo-Kan Region and pick up the $2,000 top prize.
