geocache

Geocaching (pronounced geo-cashing) is like a high-tech scavenger hunt, made possible by Global Positioning System (GPS) and the Internet. Originally developed by the U.S. Department of Defense for military applications, GPS technology has been free and available since the mid-1980s. Although many people use GPS receivers to aid in navagaition, the systems also have recreational uses, such as recording locations of caves, hiking trails, and favorite fishing spots.
