Lynne Cox has made a name for herself as a long distance swimmer. She’s swam the English Channel, the Bering Strait, and braved the frigid waters of the Antarctic Ocean. But it was during an early morning workout when she was a teenager that Cox had one of her most memorable experiences: an encounter with a baby gray whale. It’s the subject of her new book “Grayson.” Lynne Cox shares her story with Living on Earth’s Ashley Ahearn.
