On Tuesday, it was decided to postpone the East Hampton Town Trustees’ 33rd annual Largest Clam Contest until Oct. 8 because of a forecast of inclement weather on Sunday. Until then, clams beware! The contest is both a celebration of the town’s maritime heritage and a means for the trustees, who have jurisdiction over many of the town’s beaches, waterways, and bottomlands, to inform the public as to their role in the town’s governing.
