Cache is not at the posted
coordinates
But they will get you to some free parking.
I have already done a couple of caches that deal with devices
that I used regularly at one point in my life, but that have since
become obsolete. “Slip Sliding Away” (GC1MY4V) dealt with the slide
rule and “Kodak Moment #127” (GC1R35H) dealt with roll film
cameras. But devices (hard technology) are not the only things that
can become obsolete. It is also possible for approaches and
techniques (soft technology) to become obsolete. For instance, if
we were faced with the problem of multiplying 387 by 629 using
pencil and paper, we would probably scratch out something that
looks like the following:
This is the way we learned to solve the problem. It’s also the
way our parents, children and grandchildren have learned to solve
the problem. This technique must have been around forever.
However, the following diagram appeared in the “World of
Mathematics” published in 1956. It is a copy of an illustration
that appeared in a 15th century manuscript and shows how the
problem 456,789 * 987,654 = 451,149,483,006 would have been solved
at that time. The technique was sometimes called the “grating
method” because it looks like a grate.
You should be able to look at the diagram and see how it worked.
While I am old enough to have used slide rules and roll film
cameras, I’m not old enough to have actually used this method, but
you will need to use it once to find this cache. You’ll need set up
a grid and solve the problem 724,358 * 296,173 = ????.
Then, using a numbering scheme like the following, look up the
numbers needed for the coordinates. I know, I know - the Rs and Cs
are reversed!
The actual coordinates are:
N 38 37.ABC
W 121 16.DEF
A = R2, C6, B
B = R5, C2, B
C = R6, C2, A
D = R5, C3, A
E = R3, C6, B
F = R6, C4, B

Cache contains the normal log, notice and pen; prizes for FTF
and STF; and, because this is not a shorts friendly location,
stickers for trading.
