Shellfish-savvy perticipants can choose between two chowder challenges, two oyster-shucking championships (points deducted for blood on the oyster), a tying-buoy and hanging-socks contest (if you have to ask, you’re not a musselbound), and an International Shellfish Chef Challenge and Championship. Chefs from all over the world compete in the annual competition, though the last winner hailed from Alberta.
