This week on Weekends with Yankee, co-host Richard Wiese meets up with dune tour guide Rob Costa in Provincetown, Massachusetts, for an off-road ramble through Cape Cod National Seashore, taking in the magnificent views and stopping to visit one of the famous artists' cottages there. Next, we travel down to Rhode Island and out onto Narragansett Bay to hear the story of the Rose Island Lighthouse, which has been keeping watch over those waters for more than a century. For our last stop, we board a ferry to the Maine island of North Haven, a place so beautiful the locals call it "North Heaven." There, we discover a coastal farm like no other, and we bring some of its bounty back to the kitchen of Nebo Lodge, an inn and restaurant that draws guests from around the world. Back in the Test Kitchen, co-host and Yankee senior food editor Amy Traverso cooks up a cobbler made with real Maine blueberries.
