More than 100 cars were involved in a series of collisions on Hwy 99 Saturday, Nov. 3, 2007 in Fresno, Calif. At least two people were killed and dozens more were injured in a massive pileup of as many as 100 vehicles on a foggy Saturday morning, the CHP said. Eighteen big rigs were involved in a massive pileup on Hwy 99 just south of Fresno as patches of dense fog obscured visibility on the heavily traveled roadway, CHP officials said. CHP Officer Paul Solorzano Jr. said, "It looked like something out of a movie, walking up and seeing all the cars mangled and crushed." A 6-year-old boy and a 28-year-old man traveling in separate vehicles were killed in the chain-reaction collisions around 7:45 a.m. "There was probably 2-foot visibility in the fog when I got here. It was really bad," said Mike Bowman, a spokesman for the California Department of Forestry and Fire Protection. "It looked like chaos. Cars were backed up on top of each other." Thick seasonal fog known as "Tule fog" typically occurs in Central California in the late fall and winter.
