06 18 2007 - Yardan Marrero, 6, Delmaris Cora, 6, and Yanzel Marrero, 6, play on a picnic table at Ben T. Davis Beach in Tampa on Monday afternoon while waiting for lightning to pass. The water remained off-limits to swimmers Monday because of high bacteria levels and will be retested every other day. The beach could reopen as soon as Tuesday when the results of Monday's test are due back. BRIAN CASSELLA | Times
