After traveling on back roads to evade police checkpoints, Nolan Torrez looks at the burned remains of his grandparent&#39;s mobile home October 26, 2007 in Fallbrook, California. The home was part of a mobile home park destroyed by the wildfires this week in California. With improving weather conditions firefighters continued to make progress against the wildfires. The California fires caused the largest mass evacuation in state&#39;s history, burning nearly 500,000 acres, leaving a heavy toll on the county&#39;s agricultural industry and impacting an estimated cost to the state of one billion dollars. Roughly 20,000 avocado trees in the Fallbrook and De Luz areas were destroyed with a range of commodities, from oranges to eggs and even commercial flowers.
