Firefighters yesterday fought to gain ground in their fight against the fire that is burning through the heart of California’s wine country. But the powerful winds that fueled the flames over the weekend are expected to return today. The so-called Kincade fire has already burned through 66,000 acres, an area nearly twice the size of San Francisco. In southern California, more than 1,000 firefighters worked to contain a brush fire on the west side of Los Angeles. The Getty fire gets its name from the Getty Center, the hilltop art museum. The center was built to be fireproof and earthquake-proof. Yesterday, it was closed to the public but open to firefighters in need of a break.
