Stage 1 : N52°40.854 / W002°27.713
Obtain the 4 didget number on the Drain : Brickhouse Dudley
"ABCD".
Stage 2 : Final Cache
N52°40.DD(B-3), W002°27.C(A+B)(D+1)
The cache is a screw top beaker size container, in a camo bag,
containing a log book and the usual assortment of goodies. I
recommend you walk from Stage 1 to Stage 2 along the pavement and
then cut in before the end. There is no need to climb over any
fences, its on the outskirts.
