Martha’s Vineyard, where “Jaws” was filmed 50 years ago.
Endurance swimmer Louis Pugh, a British-South African has taken on extreme conditions everywhere from Mount Everest to the Arctic. He is now taking on Martha's Vineyard in honor of the 50th Anniversary of JAWS. For his swim around Martha’s Vineyard in 47-degree water he will wear just trunks, a cap and goggles. Pugh, 55, is undertaking the challenge because he wants to change public perception around sharks.
