Up Close and Personal with Winter

John Walters embarks on a midwinter expedition to the Mount Washington Observatory. It's a long ride up in a snow tractor, into below-zero temperatures, 90 mile per hour winds, and icy fog blanketing the summit. We hear the story of the observatory, meet some of the staffers, and venture outdoors, if only briefly. Visit the summit of Mt Washington yourself at http://www.mountwashington.org/
