final sweep of the area using cadaver dogs. >> mexico beach residents can return, but cannot stay there. more than 230,000 customers in florida still without power in stifling heat. residents relying on air drops for food and water. schools are still closed. in washington, liberty, jackson, franklin, calhoun and bay counties. much of mexico beach obliterated, one structure is still standing high. check out the sand palace. incredible. a three-story four bedroom on stilts remains mostly in tact. it was built to handle 250-mile-an-hour winds and the owners of the home will be on "new day" later this morning. it doesn't look real.
