On the net since 1994. Still don’t know what I’m doing.
Think of it as a treasure hunt. With pots/finds (caches) all around the world. Yes,
even near you (maybe so close, you don't even have to get into your car). All caches
try to get placed at points of interest/beautiful views.
Use of a GPS unit, guides you from the start of the hunt, to the next clue, the next
(mostly just a couple) and so on. At the end, you will find the cache. Usually a
Tupperware box, with items in it (great for kids), and a logbook. It is protocol
if you take something, you leave something. A lot of Geocachers are in it for the
scenery/views, anyhoo, and take nothing. Sign the logbook. Go home, and rest those
weary legs :)
