The GPS technique was previously the domain of the military and dedicated outdoorspeople. That policy was meant to prevent potential adversaries from using the GPS technology to launch attacks against U.S. forces or targets. Now that personal GPS units are more accurate, an intrepid group of people is using them for a new hobby.
Players obtain the coordinates of a particular stash, or cache.
They type the data into their GPS devices, then trek across the terrain to find their reward. Web site unites users Jeremy Irish, who lives near Seattle, Washington, enjoyed the experience so much that he helped start a Web site to unite geocachers around the globe. By visiting the site, participants can find cache coordinates close to their location. Once they've visited the cache, the Web site is also used as a forum for people to discuss their experiences. Geocaching can be done alone, or with a group of people.
