A wind-driven vegetation fire Friday afternoon charred an estimated 600 acres along Interstate 5, primarily to the north of Highway 140. The fire was reported shortly before 4:30 p.m. Newman Fire Battalion Chief Don Cabral said the blaze started two miles north of the I-5/Highway 140 interchange and quickly spread in the windy conditions. Resources from numerous firefighting agencies responded to the blaze. Fire crews were able to save two structures at the interchange which were threatened by the flames, Cabral said, but nine vehicles and a boat in storage behind one of the structures were destroyed. He said firefighters were on the scene until 10 p.m.
