The cache is NOT at the published co-ordinates!
However you may see some tiny horses from here if you look across the fields.
These tiny horses will not help you find the cache.
You will need to find some other tiny horses that can help you assign some numbers to each letter in the puzzle below. Once you've got the numbers, plug the digits into the formula to reveal the final location of the cache!
Good luck, and clip clop...
NORTH 52 (G-K)(D).(A)(F-C)(M+B)
