 Mission Description
This is an introduction to Letterboxing, a fun activity involving the search for outdoor treasure. The boxes you find include a stamp (usually hand-carved) and a logbook. You stamp into their book with your "signature stamp" and stamp theirs into your logbook. Letterboxes are hidden in parks and points of interest all over the world, some right near you!
