Just wanted to say I recently started a group too!! Made a group for all my fellow Geocachers! check it out and feel free to join if you cache.
for more info on what geocaching is check out
Lots of great apps for us android users in the market, and so many geocaches out in the world you will be amazed.
Join the hunt!
I'm thinking about buying one of those orange construction-like vests, a hard hat, and a clipboard so people don't look too closely when in caching in a really public place!
