The hobby began as a test of a technology change. One day after the United States turned off Selective Availability, the deliberate degradation of civilian GPS accuracy, computer consultant Dave Ulmer hid a black plastic bucket of small items in the woods near Beavercreek, Oregon and posted its coordinates to an online GPS users' group, daring readers to find it with nothing but a receiver. He called it the Great American GPS Stash Hunt; within three days two different readers had found it, and by the end of the month the pursuit had been renamed geocaching to shed the word stash's unwanted connotations.
