Blue Switch Day 2023!

Each day, hidden technologies around the world help shape our work, our play, and our futures. One such technology is GPS, or Global Positioning System technology, which revolutionized precise location information and enabled geocaching itself!

Prior to 2000, the U.S. military created and deployed satellites to produce accurate location information for military applications. Selective Availability restricted precise GPS data to the U.S. government. On May 2, 2000, the U.S. government “flipped the switch” and made accurate GPS available to all. Geocachers proudly call this day Blue Switch Day!

Let's get together and celebrate while earning a new digital souvenir!  Let's meet at the Green Lake Boathouse and Coffee Shop from 8 - 9 am to celebrate the anniversary of flipping the switch!  No purchases necessary and dress accordingly as we'll be outdoors enjoying some beautiful Green Lake views.

Who:  All of you!

What:  A social gathering of likeminded individuals to celebrate an amazing anniversary

Where:  Green Lake Boathouse and Coffee Shop.  7351 East Green Lake Dr N #5303, Seattle, WA 98115

When:  Tuesday, May 2nd, 2023  8:00 - 9:00 am

Why:  For fellowship, fun, smiles and a new souvenir!

We look forward to seeing everyone's smiling faces as we celebrate Blue Switch Day 2023!
