GPS, or Global Positioning System, was Developed by the US Department of Defense. This satellite navigation system was intended for military use and therefore the signals were scrambled, limiting accuracy for civilians use to 100 meters.
On May 1, 2000, President Clinton announced that this scrambling, known as Selective Availability (SA) would be turned off. Civilians were then able to enjoy accuracy on the order of 10 meters
May 2, 2000 the Selective Availability was turned off.
On May 3, 2000, Dave Ulmer purposed a way to celebrate the demise of SA. He hid a bucket of trinkets in the woods outside Portland, Oregon and announced its coordinates on a posting to the USENET newsgroup sci.geo.satellite-nav.
Dave Ulmer invented Geocaching in one fell swoop in that newsgroup posting.
Within a day, the original stash had been found. Within days, more stashes were being hidden all over the country. Within a month a stash was hidden as far away as Australia.
The hobby was fast on its way to being a worldwide phenomenon.
GEOCACHING WAS BORN!!!!!!
So, Come one, come all to the birthday celebration of our sport with a gathering of Cacher’s from around the “Big Sky” and share you stories.
