Enthusiasts use clues to track down hidden letterboxes, then record their successes in logbooks. This Web site explains the origins of letterboxing, gives instructions for beginners, lists clues to letterbox locations in every state and Canadian province, and has links to related sites. Similar to geocaching, but without the use of global positioning system (GPS) tools.
