This Old House sets out for Nantucket the classic way, aboard a Streamship Authority vessel. On island, they tour one of our master carpenter's first jobs, a clothing store. Linking up with designer Jock Gifford, we take a walk up Main Street, one of the finest preserved streets in America. At the subject house, a tour reveals small rooms and poor systems, but a project with a lot of potential. Accordingly, we meet island contractor Bruce Killen and then the homeowners, Craig and Kathy McGraw Bentley.
