Geocaching?

In my last blog I mentioned geocaching a couple times but did not really explain what exactly geocaching is.  Geocaching is a real world outdoor  treasure hunting activity using gps enabled devices.  Started in 2000 with one cache it has grown to over 1 million caches around the world and over 5 million geocachers.  Basically, someone leaves and object, usually a tupperware container, with a log and small objects to trade then registers it on line,at http://www.geocaching.com for example.   Other cachers look online for caches nearby enter the coordinates in their gps device and go off on a hunt. But be careful, geocaching can be quite addictive!  How many caches can you find in a day, in a week, in a year?  Or can you be the first to find( FTF) a newly placed cache? Can you find a cache in every state? On top of a 14er? Sometimes it is just the  satisfaction you feel after hunting and hunting and finally finding that cleverly hidden cache that has been staring right at you for the past 20 minutes.  Whatever it is I know I will hike higher and walk longer and explore further just knowing there is a cache nearby.
 Some of the best moments on recent trips have been finding a cache placed by a local cacher in a unique or historical location that I would of never thought to look for if it weren't for the cache.  We felt like old world explorers when we  found the ruins of a remote castle along the western coast of Ireland.  Geocaching has taken me many places, where will it take you?
