Finding the hidden treasures of Okinawa
Catholic youth group members from Kadena Air Base, Japan, pose for a photo after finding a geocoin while geocaching near Araha Beach, Japan, March 21, 2015. Geocaching is a new century treasure hunt using GPS and clues provided on a website. Geocoins can occasionally be found in geocaches and are meant to be taken, placed in different caches and tracked around the world. (U.S. Air Force photo by Staff Sgt. Marcus Morris)
