Folks around the world doing just that in one of the fastest growing pastimes. It's called geocaching.
Think of geocaching as a giant, hi-tech treasure hunt. Players use a Global Positioning System (GPS) system to "bury" and find containers (called "geocaches" or "caches") all around the world. The geocache itself is usually a small watertight container with a logbook and some kind of treasure (usually a coin, toy or some other small collectable trinket - often referred to as geoswag). The container can be as simple as a plastic 35mm film container, or as complex as a hand-made box.
Since September of 2000, geocaching has grown from 75 caches to over 670,000 active caches worldwide, with between 2 and 3 million participants.

On April 4th, 2011, the Elysburg Masonic Lodge placed their first geocache on the grounds of the Elysburg Masonic Temple. The cache is a small water-tight tupperware container with contents such as; Log Book, Bumper Stickers, masonic pins & coins, and various other items. You can track the activity of the cache by visiting Elysburg Masonic Lodge #349 Cache.
