May 3, 2000 - Dave Ulmer hid a black bucket at N 45° 17.460 W 122° 24.800, filled with videos, books, software, and a slingshot as well as a logbook and pencil. He called it the First GPS Stash. He shared the waypoint of his "stash" with the online community on sci.geo.satellite-nav.
Within three days two different people read about his stash on the Internet, used their own GPS receivers to find the container and shared their experiences online. The sport of geocaching was born!
