There is a particular sign in Westford, near where large groups
of Engineers are known to gather, with a large numeral 5 on the
right hand side. The given coordinates are not for that sign, but
they may help. On the sign, directly beneath the numeral 5, are two
lines of text.
P is the number of letters in the first line under the large
numeral.
Q is the number of letters in the second line under the large
numeral.
From the sign, the distance in meters to the trailhead is 276.8
times P.
From the sign, the true bearing in degrees to the trailhead is
23.053 times Q.
If you have previously located the Knight or the Poet, you
should have no trouble finding your way to the correct trailhead.
The trails are open from dawn to dusk. Upon successful navigation
to the trailhead, you should find a sign that has a section on it
that starts with the words "Migrating songbirds".
R is the number of letters in the first three words of the
fourth line of this section on the sign.
The true bearing from the trailhead to another nearby cache (not a
gas saver) is about 6.85 times R degrees.
The distance in meters from the trailhead to the Westford Engineer
cache is (20.21) times S.
The true bearing in degrees from the trailhead to the Westford
Engineer cache is (4.704) times S.
If you haven't found the other nearby cache yet, now would be a
good opportunity. There is at least one more cache within walking
distance also. If you find the first nearby cache, you can
bushwhack from there directly to the Westford Engineer cache by
following a true bearing of 8.558 times S degrees, but I wouldn't
recommend it. There should be plenty of birds in the area, and also
mosquitoes. But if you see a Pink Flamingo, you are probably in the
wrong place.
The cache is a large ammo box, not terribly well hidden, so when
you get to the correct vicinity it should be easy to find.
You might be wondering how to find the value of S. Do you need
more information? No, there is no missing link to this cache. If
you are drawing a blank, just relax and dig deep into your well of
mathematical knowledge, think like an Engineer, and start
calculating. Pretty soon you will have some useful coordinates,
then "Bob's your uncle," you'll find the cache.
In case you haven't noticed, this cache is a tribute to
Bushwhack Bob's amusing and challenging hides. Thanks for the
inspiration Bob!
