The other day we were out on our normal walk, when not for the first time, I noticed a large discarded can beside the road. I assumed it had become visible after the snow had melted, and this might well have been the case.
As the unofficial obersturmbanfurers of the district, this can began to bother us and the other day I picked it up to throw it onto a residents yard. Such trash is then removed when the owner turns up, but at least it's not blowing and being kicked all around the neighborhood.
The can was heavy and on taking off the lid, it was found to contain a number of toys, key rings and little handwritten notes. These implored those who removed a token to be sure to replace it.
We had found a geo-cache, which is a relatively new phenomenon. Basically if you have a smart phone with a GPS app, you can play this game of treasure seeking all over the world. The object is to use a GPS coordinate and then track down the cache. Once found you take a small token from it, perhaps leave a note and replace the token with one of your own. Millions of people are engaged in this activity. You can read all about it at http://www.geocaching.com/
Oh, I replaced the can in a not so obvious place, hidden from view.
