Down on the Eastern Shore they used to pray for bitter weal her early so the Flats would freeze and drive the canvasbacks on south. But even when it happened, not many hunters ever got to know the can quite the way the Flats man did. The best of them on the Shore today will tell you that you can't call a canvasback. Of course you can. Back in the early '40s Jim Farring would call them right off Senator Millard Tydings' decoys half a mile away. He could talk to 'em and turn 'em and comfort 'em with a lovely high-pitched whine, a sound unique. And we would sit there, man and boy, and smile and wait. He even taught me how to do it. Sometimes on a winter morning a man feels like trying out that sound again. But it catches in the throat.
