OTD in 2000, to test big upgrade to GPS accuracy day before, Dave Ulmer hid container in woods outside Beavercreek, OR. He posted about "Great American GPS Stash Hunt" on Internet, noting #GPS coordinates. The phenomenon now known as #geocaching was born. https://t.co/cQlShsHaSV https://t.co/rLdBxGV7Mv — PolitiTweet.org
