Woo-hoo!

FTF!

That is the cry heard across the land. It is the most coveted of all statistics and yet, isn't a statistic. The rush to the gathering for fame and glory is as contagious as it is frustrating. To be first is to feel the rush, this is 'the quickening.' It happens only once in the lifetime of a cache and when it happens, the energy it once possessed is gone.

In truth, only one may lay claim to the title of 'First To Find' in the great stash hunt.

Geocaching was originally similar to the 160-year-old game letterboxing, which uses clues and references to landmarks embedded in stories. Geocaching was conceived shortly after the removal of Selective Availability from the Global Positioning System on May 2, 2000, because the improved accuracy^[2] of the system allowed for a small container to be specifically placed and located. The first documented placement of a GPS-located cache took place on May 3, 2000, by Dave Ulmer of Beavercreek, Oregon.^[3] The location was posted on the Usenet newsgroup sci.geo.satellite-nav^[4][5] as 45°17.460′N 122°24.800′W. By May 6, 2000, it had been found twice and logged once. According to Dave Ulmer's message, this cache was a black plastic bucket that was partially buried and contained software, videos, books, food, money, and a slingshot.^[5] A geocache and plaque called the Original Stash Tribute Plaque^[6] now sit at the site.
