Have you ever gone Geocaching or Letterboxing?

Many people here have probably heard of Geocaching.  It's like a treasure hunt where you use a GPS device to navigate to a specific set of coordinates where someone has buried some treasure, and i guess usually a logbook that you sign when you find (dig up) the treasure.  You then replace it for the next person.

But the main point of this post was that I just read about another similar thing called "Letterboxing", which sounds more interesting to me.

In letterboxing you are not locating something using GPS coordinates, but rather by following some clues that guide you to a secret spot (you will start out knowing the general region, like in a specific park, and then follow clues posted by someone online for how to find the exact spot).  A big difference with letterboxing is that what is hidden is a unique carved ink stamp and a log book, and you will be carrying around your own custom-carved ink stamp.  So when you find it you will make an impression of YOUR stamp in the secret hidden logbook you've discovered, and make an impression of the secret stamp inside your own logbook.  In this way you have a unique set of stamps like a passport to show your journey.

I love the idea of letterboxing and how the stamps are unique and hand made and are like passport stamps showing where you've traveled.  I'm going to get my niece a stamp carving set and see if it's something she might be interested in.
