It's not every day that a monster truck runs over cars in the PX parking lot.

But last week, an official Bigfoot 4 x 4 was on hand at the Joint Base Lewis-McChord exchange for a series of demonstrations, including engine revving and car crushing. Fans young and old delighted in the spectacle. "It was like, awesome!" said Michael Palma, 4, after watching the truck flatten and fly over two cars Oct. 7.

Sponsored by Firestone, the event featured exhibitions Oct. 7 and 8 of Bigfoot #10, which weighs in at about 10,000 lbs. and features five feet tall tires. Painted in the colors of Major League Baseball, it is the only Chevy in the Bigfoot fleet, said JBLM General Manager Joey Crider, who coordinated the event. "It's the real deal," he said.

Each day's performance was preceded by a check presentation: On Oct. 7, Firestone donated $500 to the JBLM Fisher House; on Oct. 8, it donated $250 to the Boy Scouts and $250 to the Girl Scouts.

Driver Kyle Doyle and crew chief Jim Kramer (one of the original Bigfoot drivers from the 1980s) came out from St. Louis, Mo. specifically for the show. "We like to give back, and it's a nice thing to do," said Kramer, who once jumped a Bigfoot truck through the arches of the Los Angeles Coliseum.  "We highly respect our military. I don't know how they do it, but I'm glad they do. It lets us do what we do."
