Geocaching is an outdoor treasure-hunting game in which participants use a Global Positioning System (GPS) to hide and seek watertight containers filled with trinkets, hoards known as “geocaches” or simply “caches.” The improved accuracy of GPS devices allowed the pastime to develop, since the specific locations of the small containers could finally be logged and shared. Geocaches are now hidden in more than 100 countries and on all seven continents. What did the world’s first geocache contain? Discuss
