Former “Bachelorette” finalist Chris Lambton, who now has his own landscaping show on HGTV called “Going Yard,” raced back from the CMA Music Festival in Nashville to judge the WCOD Cape Cod Chowder Festival at the Cape Cod Melody Tent on Sunday. The winner of the day of chowder sampling was The Black Cat in Hyannis. Other judges included WEEI guy Mike Adams, Davio’s owner Steve DiFillippo, Lambton’s wife, Peyton Wright, and Channel 7’s Susan Tran.
