Geocaching

This is a neat idea for a new "sport" in takes hiking & treasure hunting & puts them together. Probably not the best idea for me, but a neat one nonetheless.

Goecaching:

"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. "

This site lets you type in a zip or postal code (or there are other search criteria) and it tells you about caches in your area. You have to create an account to get coordinates.
