PENSACOLA BEACH, Fla. (AP) - Thick pools of oil that washed

ashore in Florida is what forced government officials to close

about a quarter-mile section of Casino Beach on Thursday. Workers

ran yellow tape 75 yards back from the water on a day when there

would normally be hundreds of people on the sands and in the water.
