GRAND ISLE, La - Drivers operate sand sweeping machines on the beach to remove tar balls and oil in a continuing effort to restore the area back to it's original state, July 4, 2010. Workers on the beach have given the machines the nickname "sandboni" because of the way the sweepers clean the sand and the famous Zamboni ice resurfacing machine.
