Letter boxing definition
Letter boxing means an outdoor hobby that combines elements of orienteering, art and puzzle solving. Letter boxers hide small, weatherproof boxes in publicly accessible places and distribute clues to finding the boxes in printed catalogs, on websites or by word of mouth. The activity is characterized by the boxes containing a logbook and a rubber stamp. Letter boxers stamp the box’s logbook with personal rubber stamps and use the box’s stamp to imprint their personal logbooks as proof they found the box.
