What is Letterboxing?

Letterboxing is an intriguing pastime combining artistic ability with delightful "treasure-hunts" in beautiful, scenic places that the whole family can enjoy. Participants seek out hidden letterboxes by following clues, and then record their discovery in their personal journal with the help of a rubber stamp that's part of the letterbox. In addition, letterboxers have their own personal stamps which they use to stamp into the letterbox's logbook.
