The Cache IS NOT at the published coordinates.
To find the cache you will have to solve the following puzle
The cache is hidden at N 51 A.0B W 004 C.DE
(a,b and d are all double digit numbers)
To work out the coordinates you will need to use a map with road numbers to work out A,B,C,D and E. Google maps is useful for this ;) Using the road numbers to replace the letters e.g. The road that goes through Pontyberem is B4317. If the question is B4G17, G = 3. Or if the question is Q = The road that goes through pontyberem -7, it would be 4317 - 7 = 4310, therefore Q = 4310.
With those hints in tow, good luck with this challange. This puzzle is meant to be straight forward, so that anybody could solve it, using roads around the area the cache is placed. (I'm useless at puzzle caches myself, so I want to give everyone a fair chance)
A = The road from Cross Hands to Carmarthen +2
B = The Road from Pembrey to Kidwelly -389
C = The Road from Llanelli to Cardiff x2
D = Z² + (Y x Z)The Road from Penllergaer to Gorseinon = A4YZ0
E = X/2 - The Road from Drefach to Porthyrhyd B43X
(X is a double digit)
