Letterboxing is an intriguing “treasure hunt” style outdoor activity. Letterboxers hide small, weatherproof boxes in publicly-accessible places (like parks) and post clues to finding the box online on one of several Web sites. However, clues to finding some of the most highly-sought boxes are passed around by word of mouth.

There are about 60,000 active letterboxes listed on LbNA alone. Individual letterboxes usually contain a log book, an often hand-carved rubber stamp and occasionally contain an ink pad. Finders make an imprint of the letterbox’s stamp on their personal log book, and leave an imprint of their personal stamp on the letterbox’s logbook.

As the owner of a clue on LbNA, you might want to mark the clue as Retired or Missing when you pull your letterboxes from their location or receive credible news that they are gone. Use the Status button on the clue page to update the status. The clue will automatically be archived so that it doesn’t show up in normal searches. If you later replant the box, you can go back to the status page to make the clue "OK", which will activate the clue again.
