(AP) — Wildfires burning near Northern California vineyards and in the Yosemite National Park area were threatening hundreds of homes even as crews worked to contain them. While crews significantly enlarged the area they had corralled Sunday, "the steep, dry terrain continues to be a challenge" and about 515 homes remain threatened and under evacuation orders, according to a statement the California Department of Forestry and Fire Protection. The fire started Friday when a vehicle drove over vegetation that is tinder-dry from years of drought. The Amador County fairgrounds made room for displaced animals and as of noon Sunday had taken in 12 horses, seven rabbits, 15 chickens, two dogs, three cats and seven goats, said Karen Spencer, the marketing director for the Amador County Fair.
