Efforts to battle a fast-moving wildfire that swept across a Southern California freeway -- destroying more than a dozen vehicles and sending motorists scampering to safety -- were delayed because of five drones flying in the area. About 1,000 firefighters were battling the wildfire, which had grown to 3,500 acres and burned at least four structures in rural Baldy Mesa. It was 5 percent contained as of early Saturday. The freeway was shutdown for hours as motorists abandoned their vehicles when the flames spread across the freeway.
