Three lifeguards sit around an ATV close to the water of Head of the Meadow Beach in Truro, Massachusetts, a small town near the tip of Cape Cod. Attached to the ATV are two flags flying in the wind: one solid green and the other purple with a shark. While a lifeguard’s job has always been to look out for strong tide currents and stray swimmers, for years now they have had to look out for one extra thing: sharks.
Three lifeguards sit around an ATV at the edge of the beach. Flying above them is two flags: the purple shark one warns beachgoers of possible sharks and the green one means low hazard. The nesting shorebirds natural habitat is a part of the national seashore and because of that, part of the beach is blocked off to keep them safe.
