Hat tip to Silvia at Po Moyemu- In My Opinion for some great Letterboxing and Geochaching resources. She shared:

If you’ve never participated, Wikipedia offers this description:
Geocaching is an outdoor treasure-hunting game in which the participants use a Global Positioning System (GPS) receiver or other navigational techniques to hide and seek containers (called “geocaches” or “caches”) anywhere in the world. A typical cache is a small waterproof container containing a logbook and “treasure,” usually toys or trinkets of little value. Today, well over 540,000 geocaches are registered on various websites devoted to the pastime. Geocaches are currently placed in over 100 countries around the world and on all seven continents, including Antarctica.
Wikipedia also offers some great geocaching inks and resources here.
