What is Geocaching?
Geocaching is a high-tech treasure hunting game played throughout the world by adventure seekers equipped with GPS devices.
The basic idea is to locate hidden containers, called geocaches, outdoors and then share your experiences online.
Geocaching is enjoyed by people from all age groups, with a strong sense of community and support for the environment.

And then you will want to go out and buy a GPS too, so you can go and find a Geocache or two or three or four.
