As American Brad Van Liew readied himself for the ultimate solo challenge of circling the globe under sail, his children had questions. Wyatt, 6, asked about the weather and the sharks. Tate, 8, wanted to know why he had to go. She also wondered about the oceans he would be crossing and what might happen at sea. The unpredictable environment worried her. Before Van Liew raced across the start line in France to conquer what would be his third globetrotting track of victory under sail, young Tate asked if he would take a moment at the equator to send off a message in a bottle from her, with the hopes that it might be found some day and she would know where it traveled.
