Originally wanted to make this an official P.O. Box cache, but I could never find who to ask at this post office to get permission. Instead of making this one a traditional, I still thought it would be cool to have a unique P.O. Box cache, but without the box. So here we go!
At the above coordinates you will see a plaque with a date on it in the ABCD format.
