New York's Adirondack Park is larger than Yellowstone, Yosemite, Glacier, Grand Canyon, and Great Smokies National Parks combined. It is one of the largest unbroken deciduous forests on Earth, with a thousand miles of streams and rivers, hundreds of lakes, and lofty peaks. Even more amazing, most of the land within the park is privately owned, and 85 million people live within a day's drive. Yet the Adirondacks remain largely undeveloped. A WILD IDEA: THE BIRTH OF THE APA chronicles the history of the park and the founding of the Adirondack Park Agency 50 years ago.
