Proceed to A DISMAL BELLHOP (10,4) stand outside A SHABBIER
LORDLY PI (10,7) face north, walk past the CROP HOLES (9) and you
will see A BIOS STUNT (10). To the right of this is a COW FEED NEON
(6,5) look closer and you will have the prize.
Using GPS co-ords:
After decoding A Shabbier Lordly Pi (10,7) & Cow Feed Neon
(6,5) allocating numbers to the alphabet A=1 Z=26 etc. Work out
from the 6 letter word :(letter 4+ letter 5)x letter 2 and subtract
from the listed S coordinate work out from the 7 letter word:
(letter 1 x letter 7) +((letter 6 - letter 3)x(letter 3+letter 5))
and ADD to the listed E coordinate. What could be easier than
that?

I have altered the formula to find the co ordinates and included a
geocheck link - hopefully this will put to rest any problems with
the workings. (6 April 2010) Upgraded difficulty level at the
suggestion of an experienced cacher.
