A hobbie of mine...

Last summer I picked up a pretty fun hobbie called geocaching. Basically, it involves using a GPS to locate a certain location in which a treasure is hidden. It's high-tech treasure hunting.
I like it because it gets me out to places I would never have found on my own. Seems like the type of sport you really enjoy, or think is a waste of time, but if you have a GPS, I would recommend giving it a shot!
