Geocaching.com's photostream  

Geocaching is a high-tech treasure hunting game played throughout the world by adventure seekers equipped with GPS devices. A lot of us take our cameras along.
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. Search for a geocache at geocaching.com and learn more about getting started.
Share video and photos of your adventure here. We want to see where geocaching takes you.
