Conyers resident William Murrain thinks about water more than your average person — and not just because he’s on the local Water and Sewerage Authority board.Murrain has been scuba diving in the deep blue sea for more than 14 years. As a warm-water diver, he usually goes diving between the months of May and November mostly in the Caribbean, Sea of Cortez and Florida coast. "Bottom line is it’s just for fun," says Murrain about his scuba diving adventures.
