It's simple and it's REALLY short. At the posted coordinates,
you'll find a small cache containing a tool for measurement.
Retrieve this cache and tool and go to the nearest light pole.
Stand at the light pole and look DOWNHILL. Find the 3rd break in
the concrete paving. (The one right next to the light pole counts
as the first one)
From the far edge of the pavement (furthest side from the light
pole) measure 30cms in along the crack. Stand the cache container
UPRIGHT (as tall as it can be) in line with the crack, with the
next longest side along the crack length.
How long is the shadow cast from the BOTTOM EDGE (closest side
to the light pole) of the cache container?
Measure this to the nearest whole centimetre.
Take this two digit number to be "FS".
The cache can be found at: S35 10.S87, E149 08.S5F
At ground zero, please don't pull the cache out of its hidey
hole, rotate the middle bit left(anticlockwise) to remove.
Please replace all bits in their original locations and
carefully hide your tracks.
