11 years ago today, the very first geocache was hidden in rural Oregon, outside Portland. It was hidden by Dave Ulmer to test the accuracy of the global positioning system following a presidential order to disable the selective-availability feature that limited the effectiveness of the technology for civilian use. He hid a black 5 gallon bucket filled with a logbook and various items, including a tape recorder and a can of beans. Yes, a real can of beans! Which, by the way, is still around somewhere in a glass case. Here is the link to a pic of the O.C.B.
11 years has passed by and there are now over 1.3 million caches all over the world.
