Timothy Walch, is the director of the Herbert Hoover Presidential Library in West Branch, Iowa. He has a story about the history of Thanksgiving. ' So what are the facts of that first Thanksgiving? In fact, the Pilgrims of the Plymouth Colony in today's Massachusetts did share a meal with the Wampanoag Indians in the autumn of 1621, but the rest of the details are uncertain. The only documentary evidence of the event comes from the journal of Plymouth Colony's governor, Edward Winslow, who noted simply that the colonists met with Chief Massasoit and 90 of his men for a feast that lasted four days. No one worried about cholesterol or obesity in 1621!'
