Off the coasts of Maine, New Hampshire, Massachusetts, Rhode Island, and Connecticut are some of the most beautiful islands in the country-and this week on Weekends with Yankee, we visit two of them. First stop is Martha's Vineyard in Massachusetts, where we check out the historic gingerbread cottages in Oak Bluffs. Next, we're off to Maine's Acadia National Park, a 47,000-acre park on Mount Desert Island, where photographer Jerry Monkman shows us his favorite hidden spots. Then it's back to Massachusetts, where two ambitious young farmers are staking their future on growing the most delicious shiitake mushrooms outside Japan.
