Geocaching is an entertaining adventure game for gps 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.
