Have you ever thought about what makes GPS possible?
With the flip of the “Blue Switch,” or Selective Availability, GPS became dramatically more accurate, and a new kind of adventure known as geocaching became possible, turning the whole planet into a playground.
Time to hide your Blue Switch Day geocache!
It’s incredible to think that one small action could chart a course toward something so big. On May 2, 2000, that’s exactly what happened as the pivotal decision was made to flip the “Blue Switch,” leading to geocaching as we know it today.

This is all possible because of one bright day on May 2, 2000—or as geocachers call it—Blue Switch Day.
