With his family trip to Maine this weekend, President Obama becomes the first sitting president in 100 years to visit the area. Documentary filmmaker Ken Burns gave Obama a private showing of highlights before his PBS special The National Parks was aired last September. "He understood that the parks resonated in a way,” said Burns. "He spoke very movingly about the trip that he took" to Yellowstone and the Grand Canyon as a kid. Obama was apparently so moved by the experience, he took his own family on the same trip to see the famous national parks, and now has chosen Maine for their summer holiday. The Obamas are staying at Acadia National Park on Mt. Desert Island, where they’ll explore miles of hiking trails and carriage roads, and take a sunrise trip up Cadillac Mountain. At 1,532 feet, it’s not a giant, but it’s the tallest peak along the North Atlantic seaboard, and one of the first places in America to see the sunrise.
