When the marshes and ponds freeze over in November, most duck hunters hang up their guns for the season. But a few hardy waterfowlers continue to enjoy good hunting well into December on the broad waters of Lake Champlain. Late season hunting on the big lake is not for everyone. It can be numbingly cold and more than a little dangerous. But it is a uniquely beautiful time of year to be on the lake, especially when flocks of whistlers or mallards or even geese come sailing out of the snow squalls and gusts across the icy water. Host Lawrence Pyne joins the Farnham family of South Hero in their unique "rock blind" on the shores of Lake Champlain for an afternoon of duck hunting.
