I found my first geocache at lunch yesterday.  Vikki and Carter (my wife, and our dog) came over to help.  Pretty fun stuff.  It was actually a “multi-cache” meaning that the initial coordinates get you a piece in a puzzle, which leads to the next set of coordinates, etc.  Bascially it’s a treasure hunt for technologically enabled grown ups.  I can see it getting to be a habit forming kind of hobby.  From looking at the maps, there are plenty more caches near both work and my house to keep my busy for a good while.
