What's all the buzz about geocaching? Regard it as a high-tech hide-and-seek, played locally or internationally by adventure seekers of all ages equipped with GPS devices. Explorers hide--and find--waterproof containers, called "geocaches," which contain a small "treasure" and a logbook for recording the cache "visit." Latitude and longitude of the cache are posted online. A typical find is not high value and is taken by the finder who then leaves in the same cache an object of similar value. Geocaching experiences are related online as well. The official geocaching website can get you orienteering in no time. Good luck!
