While some may be worried about dipping a toe into Lake Lanier, John Fox dove into the water and swam 11 miles, all to raise awareness about keeping the lake clean and full. “The waters here mean a lot to me, so I thought what better way (to convey a message) than to swim across it?” he said in an interview last week at his Buford home. Fox, 35, made the nine-hour trek Sept. 25 from Buford Dam in the southern part of the lake upstream to Browns Bridge, which spans Lanier at the Hall and Forsyth County lines.
