Stacie and I attended a Geocaching holiday event today.  We had a great time and met a cacher who lives just a few blocks from us.  It was great putting a face to a name.  We have found many of his Geocache hides to include some his "Amendment" series which educates us about the U.S. Constitution.  Geocaching exercises the mind as well as the body.  There are puzzle caches designed for every level of experience.  Some of the puzzles are pure math while others are word plays.  You can learn a great deal about history, culture, social sciences, and humanities while participating in this treasure hunting activity.  What do you want to learn about?
