Here's a video to explain it quickly...
Here's a Tedx talk from the CEO of Groundspeak basically 'the' geocaching website...
You'll find all the other information you need to start caching here
So your challenge today is to..
1. Create a geocaching account on geocaching.com
2. Find your first cache and log your find with your new account
if you're up for more challenge...
1. find a travel bug and move it to another cache
2. create and hide your own cache
Wouldn't it be great to hide a class cache and watch all the visitors that arrive at your cache.
Please add comments about your geocaching adventures.
