Gps Treasure Hunt Played Worldwide

I was watching the H2 channel earlier about GPS and at the end they had a " did you know " fun fact. It said a ( number of players ) played geocaching. So when I got on computer , I did a search for geocaching and it said that it was a GPS treasure hunt. I guess it is played all over the world. I just learned of it , so I do not know much about it. Here is a geocaching 101 link for you to check it out. I just thought it was kinda neat and wanted to share it with you all. Have any of you ever done this ??
