Welcome to the first letterbox in Billings...

At least, since 2017.

This is not truly the first letterbox in town.
Until 08/11/2016 we had GC5B95K Great Play!
Until 03/29/2016 we had GC5B6GK El Sombrero
And until 08/20/2015 we had GCV9BH Stamp It

These previous caches, and this one, fall under the type category of 'letterbox hybrid'.

Letterbox Hybrids are based on an older kind of container search, called letterboxing. Because letterboxing began in 1854, before GPS existed, the finder follows written instructions to discover the container.

Each letterbox contains a logbook, and a rubber stamp. When letterboxers find the container, they stamp the logbook with their personal stamp, and also stamp their own notebook with the stamp from the letterbox as a souvenir of their visit. The stamp and logbook remain in the letterbox for the next visitor to use.

Some letterboxes are mixed with multi or unknown style geocaches so there are multiple stages or even puzzles to solve to find the final. Others are just at the posted coordinates like a traditional cache. The cache page of a letterbox will tell you what to expect.

This geocache is at the posted coordinates, just like a traditional geocache, with a paper log and rubber stamp inside. The rubber stamp is not a trade item and needs to stay in the geocache. Ink pads dry out so I recommend bringing your own. If you forgot to bring your stamp, or don't have one, you can still log this as found by signing the log like normal, though it is encouraged to do some sort of stamp along with it. Some people ink their finger and stamp their fingerprint.
