The Adopt-a-Trail program, a national effort to recruit volunteers to help maintain thousands of miles of public trails, has taken off in southeastern Idaho. Participation has increased by 200 percent since 1992, in large part because of Michael Bargelski, an artist who lives in Idaho Falls. Each person who "adopts' three miles of trail in the Targhee National Forest gets one of Bargelski's wildlife prints. Volunteers clear and do basic repairs to a trail, and report more serious damage to the Forest Service.
