On May 2, 2000, at approximately midnight, eastern savings time, the great blue switch controlling selective availability was pressed. Twenty-four satellites around the globe processed their new orders, and instantly the accuracy of GPS technology improved tenfold. Tens of thousands of GPS receivers around the world had an instant upgrade.
The announcement a day before came as a welcome surprise to everyone who worked with GPS technology. The government had planned to remove selective availability - but had until 2006 to do so. Now, said the White House, anyone could "precisely pinpoint their location or the location of items (such as game) left behind for later recovery." How right they were.
For GPS enthusiasts, this was definitely a cause for celebration. Internet newsgroups suddenly teemed with ideas about how the technology could be used.
On May 3, one such enthusiast, Dave Ulmer, a computer consultant, wanted to test the accuracy by hiding a navigational target in the woods. He called the idea the "Great American GPS Stash Hunt" and posted it in an internet GPS users' group. The idea was simple: Hide a container out in the woods and note the coordinates with a GPS unit.
The finder would then have to locate the container with only the use of his or her GPS receiver. The rules for the finder were simple: "Take some stuff, leave some stuff."
On May 3rd he placed his own container, a black bucket, in the woods near Beaver Creek, Oregon, near Portland. Along with a logbook and pencil, he left various prize items including videos, books, software, and a slingshot. He shared the waypoint of his "stash" with the online community on sci.geo.satellite-nav:
N 45° 17.460 W 122° 24.800
Within three days, two different readers read about his stash on the Internet, used their own GPS receivers to find the container, and shared their experiences online. Throughout the next week, others excited by the prospect of hiding and finding stashes began hiding their own containers and posting coordinates. Like many new and innovative ideas on the Internet, the concept spread quickly - but this one required leaving your computer to participate.
Within the first month, Mike Teague, the first person to find Ulmer's stash, began gathering the online posts of coordinates around the world and documenting them on his personal home page. The "GPS Stash Hunt" mailing list was created to discuss the emerging activity. Names were even tossed about to replace the name "stash" due to the negative connotations of that name. One such name was "geocaching."
Original contents were:
Delorme Topo USA and 2 CD Roms, a cassette recorder, a "George of the Jungle" VHS tape, a Ross Perot book, 4 $1 bills, a slingshot handle, and a very famous can of beans

A mi me va muy bien interpretando la música autóctona de PR como para explicarle a mequetrefes que ni siquiera viven en PR sobre cómo tocar bien un aguinaldo. He salido en presentaciones que tú en tu miserable vida no vas a salir con esa actitud y esa porquería que llamas "tocar".
