Some of you may have heard of (or even had the priviledge of doing) a reverse geocache. The idea behind it is that you are handed a box, you press a button and it tells you how far you are from the location, but not which direction. Once you get to the correct location, the cache will open. This Wherigo is a version of a reverse geocache, but it is an electronic version and there is a container to find at the end.
So, how many times will you have to push the button to make the find? How far will you have to walk?
The cartridge needed to play this Wherigo can be found with the related webpage link on this listing.
