"Geocaching is an entertaining adventure game for Global Positioning System users. Participating in a cache hunt is a good way to take advantage of the wonderful features and capability of a GPS unit. The basic idea is to have individuals and organizations set up caches all over the world and share the locations of these caches on the Internet. GPS users can then use the location coordinates to find the caches. Once found, a cache may provide the visitor with a wide variety of rewards. All the visitor is asked to do is if they get something they should try to leave something for the cache." I first became aware of Geocaching when I got e-mails from players letting me know that "Get Out of Hell Free" cards were a common "reward" packed in the caches. When I read up about how it all works, I thought it sounded like a very fun activity. From This is True for 5 September 2004 Suggestions for further reading:
