Geocaching - Very interesting

GPS 'treasure hunting' ... sort of. There are many different ones. Here is a rather annoying video re what it is.

From the web site itself:

"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."
