All About Geocaching
Geocaching is an outdoor activity 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 (usually a tupperware or ammo box) containing a logbook. Larger containers can also contain items for trading, usually toys or trinkets of little value. Geocaching is most often described as a "game of high-tech hide and seek", sharing many aspects with orienteering, treasure-hunting, and waymarking.
Geocaches are currently placed in over 100 countries around the world and on all seven continents, including Antarctica. As of November 9 2009, there are over 937,510 active geocaches over the world.
