Ho! Ho! Ho!
(The cache IS NOT at the given coordinates)
My Christmas gift to you - a letterbox cache.
Remember the stamp stays with the cache and is not swag.
Head to the listed coordinates. I hope you won't be needing one of these while looking for the cache but you know where to go if you do.
Find the yellow sign on the wall in the under cover courtyard. Visible from the street.
There are five lines of writing. Let the number of letters in each line equal A, B, C, D, & E respectively.
From the given coordinates, project:
The Angle = (E-D) D . E C
The Distance = (Bx10) . D (Ax4 +1) metres
(they are decimal points in there)
Now make your way to Ground Zero.
Please be gentle.
The person who lives here knows about the cache. You do not need to search any plants.
