On May 2, 2000, just past midnight, the U.S government discontinued its use of Selective Availability in order to make GPS more responsive to civil and commercial users worldwide.
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.
Prior to this date, only the military had the ability to receive accurate GPS readings.
Now, the world and all its wonderful people could pinpoint their precise location.
For reasons unknown, this is often referred to as the flipping of the “Big Blue Switch”.
The very next day, a computer consultant named Dave Ulmer hid a black bucket in the woods near Portland, Oregon. Along with a logbook and pencil, he left various prize items including videos, books, software, and a slingshot, then posted the coordinates online.
Three days later, the container was located by Mike Teague.
Now, seventeen years later, geocaching has become a global phenomenon to get off the couch and get outside.
In the past 22 years, geocachers have reached many milestones including 3 million active geocaches, 7 million active geocachers, and over 22 million awarded favorite points.
The Big Blue Switch souvenir is one more way to celebrate the evolution of geocaching*!
This event will require a little stealth, once at ground zero, you will need to track down the event organisers and if it's outside, then Abby will be present to assist, of course for the cost of a dog biscuit.
Looking forward to a cache up to new and long suffering cachers.
Theme for the event BLUE, but this is not to be classed as an additional event requirement and is just for grins and woofs.
