The organization that’s developing a backcountry network of huts along 180 miles of trails in western Maine has a new executive director. Maine Huts and Trails has named Charlie Woodworth to head the Kingfield-based organization. Woodworth is an avid outdoorsman and a longtime Yarmouth resident who is relocating to Kingfield. He replaces Nicole Freedman, who has returned to Boston to be executive director of bicycle programs for the city. Maine Huts and Trails was formed with the long-term aim of building 12 overnight shelters and non-motorized trails stretching from near the New Hampshire border to the Moosehead Lake region. Each shelter has a main lodge, private rooms with beds, hot showers and home-cooked meals. So far, the organization has built four huts and created 80 miles of trails.
