FARMINGTON — They are big, loud and out to destroy.

The monster trucks are in town, and they are expected to perform like their name implies they should — lots and lots of crushing and roaring.

"The sheer weight of these trucks will crush a car," said Tod Hammock, event coordinator for the Monster Truck Nationals.

The Monster Truck Nationals will be held at McGee Park in Farmington on Friday and Saturday. The show is part of a nationwide tour featuring five monster trucks and two motocross motorcycles that perform wild and raucous tricks for audiences.

Both shows will begin at 7:30 p.m., with doors opening at 6 p.m. Advance tickets are $10 for children 12 and under, and $17 for adults 13 and over. Tickets are a dollar more at the door.

"Just the percussion alone," Hammock said, "it's impressive."

He said the event is family friendly and fun for everyone who attends.

The trucks arrived Thursday in Farmington, with one of the most popular trucks, Bigfoot, rolling out for display at Northern Edge Navajo Casino on Thursday evening.

"That boy — he's been waiting to see this truck for an hour," said Jim Kramer, Bigfoot crew chief.

A small crowd gathered Thursday around the semitrailer which carries the truck crosscountry during the tour.

As Hammock and driver Kevin Kosala unloaded the truck, people snapped photos of the 12-foot-high vehicle and its six-foot-wide tires.

The 1,250-horsepower engine let out a deafening roar as the truck slowly rolled down the semi-trailer's ramp.

"We try to make everyone's experience with the trucks special," said Kramer. "Once you've experience it, you're a fan for life."

Kramer is one of the few people who can say he has dedicated his life to the sport as more than just a fan. Kramer was the first driver of the first monster truck, which also was named Bigfoot.

The current Bigfoot is owned by the same person who owned the original, though it is the 11th version of the original, which came out in the 1970s.

"I was the first guy," said Kramer, who since has driven the Bigfoot in Budweiser commercials and thriller movies such as "Tango and Cash," "Roadhouse," and "Police Academy 3."

"It's just fun," said Kramer.
