Retirement communities built on golf courses, semi-rural race horse stables and other usually serene sites were engulfed by flames as the San Diego area became the latest front in California’s wildfire fight.
It exceeded 6 square miles (16 square kilometers) in a matter of hours and burned dozens of houses as it tore through the tightly packed Rancho Monserate Country Club community in the small city of Fallbrook, known for its avocado orchards and horse ranches. Three people were burned while escaping the flames, said Capt. Nick Schuler of the California Department of Forestry and Fire Protection.
Meanwhile, firefighters in Ventura — 130 miles (209 kilometers) to the north — tried to corral the largest and most destructive fire in the state, which has destroyed 430 buildings. The so-called Thomas Fire has grown to 180 square miles (466 square kilometers) since it broke out Monday. Fire crews made enough progress against large fires around Los Angeles to lift most evacuation orders. 
Fire crews look on as they fight a wildfire Thursday, Dec. 7, 2017, in Bonsall, Calif. The wind-swept blazes have forced tens of thousands of evacuations and destroyed dozens of homes in Southern California.
