JAMUL, CA - OCTOBER 24: A US forestry firefighter cools a burning modular home to protect a nearby structure in Deerhorn Valley as the Harris Fire continues growing beyond 70,000 acres on October 24, 2007 near Jamul, California. Southern California is being ravaged by numerous record wildfires as Santa Ana Wind conditions push them into communities surrounded by native Chaparral habitat that has been dried by the driest rain season since records began 130 years ago. The fires are shaping up to be the worst wildfire event in San Diego County history. As many as 500,000 people have been evacuated from their homes.  (Photo by David McNew/Getty Images)
