Here is a great hobby, its called Geocaching pronunced "Geo-Cashing" like a check. Geocaching is an entertaining adventure game for GPS users. Participating in a cache hunt is a good way to take advantage of 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 found this on the Internet and realized there are Caches hidden right here in Chillicothe and since I already have a handheld gps unit, I went looking for them.
