Crowds estimated at over 1,000 packed the area behind Yucca Yalley Chrysler yesterday for a fun, free spectacle yesterday. The Monster Truck “Raminator,” which had been on display at the dealership during the week, showed its stuff in a demonstration at about 2 p.m. The crowd whooped and hollered as the 2,000 horsepower modified truck flattened three junk cars lined up.
