Final answer:
The Original Stash Tribute Plaque marks the birthplace of geocaching, an outdoor treasure-hunting game created in 2000 where participants use GPS to hide and seek containers.
Step-by-step explanation:
The "The Original Stash Tribute Plaque" is a historical marker located at the site where geocaching was invented in 2000. This outdoor recreational activity involves participants using a Global Positioning System (GPS) receiver or mobile device to hide and seek containers, called "caches" or "geocaches", at specific locations marked by coordinates all over the world. Dave Ulmer, a computer consultant, wanted to test the accuracy of GPS by hiding a navigational target in the woods. He called the idea the "Great American GPS Stash Hunt" and posted it in an internet GPS users' group. The idea was simple: Hide a container out in the woods and note the coordinates with a GPS unit. The plaque marks the spot of the very first cache placed on May 3, 2000. This birth of geocaching has led to a diverse and global community of enthusiasts who participate in the activity.
