Sad Excuse Mystery Cache

I was on FS194 and just decided to plant a cache. Sad Excuse, for where it is. I used a small, cheap container. Sad Excuse for what it is.

The cache is not at the posted coordinates. Sad Excuse for coords.

To get the actual coordinates, you must solve the coordinates for the cache Jack's Watering Hole, GC3B3R5. Use the solution values in the following:

U= B-4

V= C+2

W= A-2

X= C+D+2

Y= C+E

Z= D+E

The actual coordinates for Sad Excuse are:

N 34 21.UVW

W111 33.XYZ
