St. Patrick's Day comes around on March 17, but the Olde Towne Slidell Association kicked off the celebration Sunday with its 45th annual St. Patrick’s Day Parade, throwing a load of loot including 5,000 heads of cabbage, 10,000 onions, 25,000 potatoes and 15,000 carrots. More than 50 units and 300 riders took part on the damp day.
