Blue Switch Day 2024
On May 2, 2000, the Selective Availability (SA) was cancelled and made the accurate GPS (Global Positioning System) available to all. Later, on May 3, 2000, the very first "cache" was released and found recorded. The day become the "flipped switch" day of geocaching. How amazing!
2000 年 5 月 2 日，這天選擇性可用/選擇性誤差 (SA) 被取消，向所有人提供精確的GPS(全球定位系統)。後來，2000 年 5 月 3 日第一個「地理尋寶」(座標) 被釋放，並被發現記錄下來。這一天世界按下了地理藏寶的開關。多麼驚人！
