Richard Cook looked the part with his short cropped hair, weathered face and ramrod-straight military gait. The old salt would fool no one. The real giveaway was the navy blue shirt with five rows of campaign ribbons complete with six battle stars on his chest. Underneath, embroidered in gold, it read: U.S. NAVY. Down the left arm of his long-sleeve shirt were the names of seven Vietnam cities. Even more interesting, also embroidered in gold, were four more lines of words in gold that read: “CAN’T TELL YOU.”
