Karl and Suzy Wagner of Del Mar, with a copy of The Log at Trawler Fest, gather information on the Big Loop. Trawler Fest is a series of boat shows moving from venue to venue. The Great Loop is a circumnavigation of more than 5,000 miles through the Intracoastal Waterway, Great Lakes, canals and inland rivers. The Wagners, members of Southwestern Yacht Club, enjoy sailing their Hunter 410.
