You may have seen NASCAR races on TV, and maybe have been lucky enough to see stock car races in person, but you've NEVER seen this!

Coming this Saturday to Columbia Motor Speedway in Hermiston are the Rolling Thunder Big Rigs! The only U.S.-based semi-truck racing association Rolling Thunder will present at least 8-10 of the diesel monsters racing around the 3/8-mile just north of Hermiston. Two of the trucks put on a mini demonstration last weekend at the track, and were clocked at amazing speeds of over 65 mph average lap speed on the track!

These trucks race all over the Pacific Northwest, and will be making their first trip ever to the Mid-Columbia.  Time Trials are at 5 p.m. with racing to follow. Click here for ticket information for Columbia Motor Speedway.
