WHAT'S GEOCACHING AND WHY SHOULD I CARE?
Geocaching is a real-world, outdoor treasure hunting game using GPS-enabled devices. Participants navigate to a specific set of GPS coordinates and then attempt to find the geocache (container) hidden at that location. The containers could be anything from plastic boxes to specially designed objects designed to blend in, providing more of a challenge. You should care because it's good exercise and gives you excuse to peel off the sofa once in a while. Once you've found one, it's hard to ignore.
Caches usually contain a log, where you can write your username and the date found as proof of your discovery. Players usually follow etiquette, which means replacing the cache as found and reporting any problems to the cache owner. Almost anybody can hide their own cache providing a few rules are met, but these aren't taxing and help the sport grow. There are a number of apps (including the official website) which make your hunt easier and more rewarding.
There was a topic dedicated to geocaching that was made about five years ago, but it didn't receive too many replies. Hopefully it's still in vogue enough to garner players. Chances are, if you're reading this, there's one not too far from you. There are literally millions of them worldwide and you'd be amazed to learn what was lurking on your route home all this time.
