When I went for a walk round this reservoir I noticed there were no caches hereabouts so decided to create a little puzzle intended to exercise mind and body.
The given co-ordinates are for the parking place from which you can start your little adventure after solving the puzzle.
To find A to F you need to calculate the alphabetical value (A=1 Z=26) of:
A - one without purpose or direction;
B - one lacking strength of character;
C - one lacking elegance or charm;
D - one having no purpose;
E where you would find them all;
F - who put them there?
G is the total of A to F.
You then need to calculate the following co-ordinates:
N 54 44.B+C+D+E+F W 002 14.G
If you choose to go there you do so at your own risk but will not find the cache. From there you should look round you until you see something you would find useful. This is where the cache is hidden.
NB. In the spirit of this cache I am not using any form of checker. You'll have to walk!
