I have been joining a friend of mine on many geocache adventures, but signed up myself last Saturday. Who else has a geocaching account and has been exploring the nature and/or city?! For the people not familiar with Geocaching: Link to Geocache Website Link to Geocache Guide !
That's so cool! I've never even heard of it before, but it sounds amazing. Won't be signing up for it right now, because I'd want to do it with someone rather than on my own, but that's such a great idea.
It's a sort of treasure hunt with coördinates. I've been to places in my hometown where I've never been before, even though I live here for 22 years!
