Hikers who prefer clothes are not happy.
Rangers and police warn that people caught outdoors in the altogether could be charged with indecent exposure. Managers of the Appalachian Trail, where the tradition is sometimes observed by those trekking from Georgia to Maine, also discourage nudity.
"It's just rude," said Brian King, spokesman for the Appalachian Trail Conservancy in Harpers Ferry, W.Va. "People are out there hiking with their kids and families, and there are Girl Scouts and Boy Scouts."
