We often underestimate our reliance on GPS (Global Positioning System), yet, over the course of 24 years, it has fundamentally reshaped our lives and the world we inhabit.
Imagine how different our daily routines would be without GPS technology. Among many other things, paper maps would be necessary to navigate from point A to point B and turn-by-turn delivery tracking would be impossible. Notably, geocaching would never have come into existence.
This transformation traces back to a pivotal moment on May 2, 2000—dubbed Blue Switch Day by geocachers. Before May 2000, Selective Availability restricted accurate GPS technology to military use. However, on Blue Switch Day, the U.S. government made a landmark decision which opened up accurate GPS technology for public use. Geocachers commemorate this day as a milestone, marking it with pride and celebration.
Looking forward to celebrating this game changing day with my geocaching friends.
