Visit Shelburne Farms, a nonprofit education organization whose mission is to cultivate a conservation ethic for a sustainable future. Tour the 1,400-acre working farm and National Historic Landmark on the shores of Lake Champlain in Shelburne, Vermont. One favorite spot is the dairy which supports about 110 milking cows, all purebred Brown Swiss. The milk is crafted into an artisanal cheddar on the property. The primarily pasture-based dairy defines the working landscape and is part of the campus for learning about sustainability.
