This is not a post about caching for applications, but a different kind, the kind where people all over the world hide artifacts and you must search and log them. Welcome to the world of Geocaching!
I've been introduced to this recently and must admit I like the concept very much. It brings you to places you'll probably never end up otherwise, even in your own neighbourhood, and just recently while visiting Berlin. Anytime I see someone strolling around at the same spot for a while, I know what this person is doing now! You can also hide your own caches, so that's what I did. My first geocache called 'De dokwerker' has been published. So if you're ever in Gent (Belgium), go and find it! :)
