| Letterboxing | Game A game similar to geocaching but much older. Letterboxes are found through a series of clues rather than GPS coordinates. The boxes contain a logbook and a stamp (sometimes hand carved) which is used to mark the letterboxer's own logbook. The letterboxer in turn marks the logbook inside the letterbox with his or her own stamp. Letterbox Hybrids are geocaches that incorporate elements of letterboxing.
