This is a LETTERBOX HYBRID geocache. Letterboxing is a precursor of geocaching, using compass bearings or other clues to lead the seeker to the letterbox. The cache contains a logbook and a stamp. If you wish, you may stamp your personal journal with the rubber stamp in the letterbox (cache); then you may stamp the logbook with your personal stamp if you have one - if you don't have a stamp, just sign the logbook. But, please be sure to leave the stamp, logbook, and inkpad in the container.
Your looking for a medium container. The cache is located at the posted coordinates. As with all of my new caches, there is a trackable waiting for the FTF to pick up and move along. Safe caching!
