Park Service: Increasingly Voluntary

Not only is the National Park Service raising fees, it's also increasingly likely that the people who are on the job in the parks -- performing day-to-day tasks and answering questions from visitors -- are volunteers. Last year at Yellowstone, the Jackson Hole Star-Tribune reports, more than 2,500 volunteers worked 100,000 hours -- the equivalent of 50 full-time employees.
