Geocaching, a high-tech treasure hunting game, is played world-wide by adventure seekers equipped with Global Positioning System (GPS) devices. Players locate hidden containers called geocaches and share their experiences online. Popular with people of all ages, geocaching strengthens communities and fosters an interest in the environment.
