      When Ray Necochea was building his dream house four years ago, he wrote the story of his life

on a wooden beam below the rooftop, hoping a future relative might discover it.

      With that beam and everything else inside the home destroyed in the firestorm that has struck

southern  California this week, the 55-year-old electric company worker is promising to rebuild on

the same hilltop  overlooking nearby farms and mountain-tops.

      Such scenes of pain and hope for the future are taking place across southern California, where

officialsare gradually lifting evacuation orders to allow residents back into areas damaged by some

of the worst     fires in the state's history. Officials say the fires destroyed more than 2,000 homes,

often with such fierceness that little remained.

       As a "troubleman" or repair worker for the San Diego Gas & Electric Company, Necochea had

already seen his destroyed home on Monday, but returned on Thursday and mused(沉思) philosophically

on the nature of life and loss.

      "I was so shocked," he said as he looked across what had once been a 4,600 square foot,

three-bedroom home with a swimming pool in an area where the sounds of cows, coyotes and birds,

not the din of modernity, are the soundtrack of daily life. "It was just a burning heap of ash. It was a

horrible feeling; I don't   wish that on anyone."
