This is a Geo-Post Office!
It is used to swap letters and postcards between geocachers!
Here's how it works:
Caches are intended to hold postcards and trackables. Each postcard will have a short message and a forwarding address on it. The address will contain the person's name that you are trying to send the postcard to, their home city, and a destination cache. The idea is to move postcards between caches until they reach their destination. When you move a postcard or message from one place to another, let the person who it's being sent to know where you moved it, because they might be close enough to go and pick it up. If you move a postcard from one Post Office to another, please move it closer to the destination!
You can send a message to anyone you want!
How do you get started? Easy! Just write up your postcard and drop it in the Geo-Post Office! No need to spend your hard-earned cash on a postcard at the store, the cache has a supply of blanks, or, if you choose, you can print and laminate a huge variety of postcards off the internet. There are no tradeables in the cache, it is for mail and trackables only.
Just a short walk to locate the lock-and-lock plastic container. The area of the cache site offered lots of devious hiding spots, but since we are concerned with efficient movement of the mail, the hiding spot is fairly simple. Please be sure that the cache is hidden from view when you leave.
I've rated the terrain at 1.5 because of the absence of a well-defined trail to the cache, but no heavy bushwhacking is involved.
