Please download the Geocaching app and set it up. Also from what I understand you are supposed to bring something to replace what you find in the caches so please bring something small and non valuable to replace the cache. According the app, there are caches near campus so let's find them! Geocaching is an outdoor recreational activity, in which participants use a Global Positioning System receiver or mobile device and other navigational techniques to hide and seek containers, called "geocaches" or "caches", at specific locations marked by coordinates all over the world.
