So I was just interested by this idea of geocaching from Andy's story so I looked it up to give me a better idea of how it's used and such. One of the sites I found has all sorts of examples of geocaching and "puzzle caches" including quite a few from right here in Alabama.
I put the link to one of these puzzle caches in the title. It's one that I found particularly interesting, as it is entirely based around the UA campus. Just thought I'd share it as it seems pretty cool.
Scroll down the link to get to the good stuff.
