This is a very straight forward multi cache.
The coordinates should pinpoint a location where 2 numbers can be seen. The higher of these is X, the lower is Y.
The values for X & Y should be entered into the following sums to find values for A, B, C, D, E & F:
A = (2 x Y)
B = (Y÷ 2) + X
C = (4 x X) – (5 x Y)
D = (4 x X) – (3 x Y)
E = (2 x Y) - X
F = (2 x Y) – (X – Y)
These should then be entered in the following to give the final coordinates:
N53°42.ABC’ W002°38.DEF’
Please be aware that the road can be very busy and doing this cache as a drive by is not recommended.
