NORTH LIBERTY— While some Scouts might spend an afternoon removing trash from local parks, Girl Scout Troop No. 5664 in North Liberty is leaving stuff behind.
The Girl Scouts are leaving letterboxes, an outdoor treasure hunt similar to geo-caching. The hobby offers all ages an excuse to go outside and explore. Letterboxers follow clues (these days, the clues are online) to small, weatherproof boxes containing a stamp that is hidden in a publicly accessible area. Once they find the letterbox, they collect a copy of the stamp, leave their own mark and return the box to its hiding place.
