A collegue told me about this curious standing stone in the middle of a housing estade and when I went to check it out, I immediately thought: "This needs a geocache". The historic stone dominates the whole area with streets called "Caiystane Terrace", "Caiystane Drive" etc. Unfortunately there is no place to hide a cache nearby, so you will need to travel a bit.
The cache is hidden at: 55°54.ABC'N, 3°1D.EFG'W
To work out the numbers, you will need to locate the sign next to the stone and count the number of letters according to the following list:
A - 10th word
B - 7th word
C - 3rd word
D - 1st word
E - 4th word
F - 2nd word
G - 39th word
So, for example, if the sign said: "Geocaching is fun", C would be 3.
