Stifling heat is adding to the misery of Southern California fire crews. They're battling wildfires burning out of control across 17-thousand acres of land in three counties. More than 23-hundred firefighters are on the lines, facing another day of 100-degree temperatures. No homes have been lost, but dozens of people have been evacuated. At least five firefighters have suffered heat-related injuries and one fire captain was killed in a wreck yesterday on his way home. A fire burning near the Angeles National Forest is described as very dangerous and very erratic -- and still advancing. One man who left says he took his dog, cat, stereo, clothes and toothbrush.
