On the 400^th anniversary of the first Thanksgiving, for some Native people, it’s a Day of Mourning.  On Radio Times, Historian DAVID SILVERMAN tells the story of contact between the Wampanoag and the Plymouth colonists from the Indian perspective in his new book, This Land Is Their Land.  In it, he explores how the Wampanoag felt about the English, the tenuous relationship that developed, and their continuing struggle for self-determination.  To hear the program, click here.
