Chowdafest. Chowdafest VIII: The War at the Shore By Wendy Logan. On October 11, some 40 chefs, hailing from New Jersey to Connecticut to Vermont, and even as far away as Seattle, Washington, will descend on Sherwood Island State Park for a battle of the ladles. It’s Chowdafest time and whether you’re a lover of the creamy, New England clam original, the Manhattan red, or something slightly more outside the box, soup’s on, and you’re invited to be a judge.
