The buildup is on to this weekend's monster truck rally at L.I.F.E. Fairgrounds. The thousand-pound car-crushers have come in from around the country for Monster X, which is set for Friday and Saturday. Trucks were on display tonight at NAPA Auto Parts on Calton road and Mines road, where people can also purchase tickets for the rally. Prices range from $10 to $30. Fans can come to watch all the metal bending action and can also get a chance to meet one of the monster truck drivers and learn what it takes to get in the drivers seat.
