Letterboxing is an outdoor hobby that combines elements of orienteering, art, and puzzle solving. Letterboxers hide small, weatherproof boxes in publicly-accessible places (like parks) and distribute clues to finding the box in printed catalogs, on one of several , or by word of mouth. Individual letterboxes usually contain a notebook and a rubber stamp. Finders make an imprint of the letterbox's stamp, either on their personal notebook or on a postcard, and leave an impression of their personal stamp on the letterbox's "visitors' book" or "logbook" — as proof of having found the box and letting other letterboxers know who has visited. Many letterboxers keep careful track of their "find count".
