HAGERSTOWN, Maryland - Every year on the first day of summer, a few beekeepers across the United States expose virtually all of themselves to insects, scrapes and thorns for the pleasure of bonding with nature au naturel. They call it Naked beekeepers Hiking Day. "There's no way to explain it until you experience it," said Andrew Williams, 28, a machinist from Warren, Pennsylvania, who first hiked naked six or seven years ago. "It's not about being lewd and crude and all that. It's just enjoyment." This year, the summer solstice falls on a weekend - this Sunday. Father's Day. most beekeepers wear clothes said a local reporter. Hikers who prefer clothes are not happy.
