Geocaching (Not geocatching, as I thought for the first 3 months)

If you haven't already heard, there are THOUSANDS (just look to your left a few pixels to see) of hidden treasure boxes places throughout the world that you can find, take something out of, and replace with something else - trade hunting, if you will.

All you need: A smartphone!

There could be one in your neighborhood, because there was one in mine, and.........come on, the population is in the few thousands!

Sorry for the terrible screenshot, Chrome OS doesnt have a selection screenshot YET :D
