A secure location for travel bugs.
In order to gain entry, you will need to use your vision to determine the correct characters for the lock. A tool is provided to assist you. Once you have the information, you must determine the correct order.
Contained inside this letterbox are a stamp (for the cacher to stamp their own logbook), a logbook (for the cacher to use their personal stamp), and an inkpad. None of these are swag. Please leave them for the next cacher. Inkpads do dry out, so feel free to bring your own ink. Or just sign the logbook if you do not have a stamp.
Many thanks to Dr. Landis for the approval to place this cache at this location.
