Being that I am a bit of a
computer geek....OK...very much a computer geek, and an Information
Technology Instructor, I thought I'd let my true colors show in
this cache.
A computer breaks everything it does down to two
possible values, or states: On (electical current present) or Off
(electrical current not present). We humans represent this with 1s
and 0s, with a 1 representing "on" and a 0 representing
"off".
This is known as the binary number system because it uses only two
possible values for each digit. By combining the word "binary" and
"digit" we get another common term to computer geeks:
>Bit
, which means Binary Digit
Usually, when one first
learns about binary it seems difficult, but after working with it
for awhile it really isn't all that bad. If it was, computers
couldn't handle it!
This cache will require you to use binary to convert the coords to
the base-10 numbering system that we've all used since we first
started counting.
OK, so how does one count in binary then? How can we convert from
binary to base-10 and vice-versa?
With binary, every bit value is double the bit value on its
immediate right. This is just another way of saying that every bit
is a factor of 2, with the right-most digit representing
20, the next representing 21, then
22, and so on.
So the first bit has a value of 1, the next bit to the right has a
value of 2, then 4, and so on. In base 10 we have ones, tens,
hundreds, thousands, etc. In Binary we have ones, twos, fours,
eights, sixteens, etc. With binary all you have to do is add. By
adding the bit values that are set to "1" together you get your
base-10 equivalent!
Sometimes it helps to build a chart when you first start using
binary so you don’t have to remember all the powers of two and try
to do math in your head. Besides, that’s what computers are for
anyway, right?

The top row in the chart
represents the placeholder values for 8 bits. Every web site on the
internet boils down to a series of numbers, known as an IP address,
which follows the same format as the chart above.
To convert binary to base-10, all you do is add the decimal
equivalents wherever there is a “1” in the chart. Let’s work
through some examples: The next four rows in the table represent
binary numbers.
The second row (the first row in green text) is binary 00000001, or
1 in the base-ten numbering system. We don’t have to use preceding
zeros in binary, but it is sometimes easier to understand and learn
if you do so.
The third row, 00001100 is equal to 12 (8+4) in base 10. So 1100 in
binary is equal to 12 in base-10. Looking at the chart above, you
see that the bits under 8 and 4 are both set to 1. You add the
value of the bits, 8+4 and come up with 12. That’s all there is to
it.
Next line: 10000011, or 131 (128+2+1)
The next line is even easier. It is set to all 1s, or 11111111.
Whenever a binary number is set to all ones, the base-10 equivalent
is always equal to one less than the next bit value to the left. In
this case the next bit value to the left is 256. 256-1=255, so
11111111 in binary = 255 in base-10.
Hopefully that's enough to get you started. If not, or if you are
just itching to learn more, then there is a wealth of information
here
and
here as well as many other places on the internet.
The coords in the listing will take you to a parking spot that is
very close to the location of the cache. You are searching for a
waterproof match container containing only a log and pencil. Please
ensure that you replace the container in the exact same spot and
that it is pushed down snug so as not to be easily visible, as this
cache is in an area of extremely high muggle activity. Also, the
lid on this particular container seems to cross-thread easier than
most, so please use care when screwing the lid back on to ensure a
good seal. Best hunting times in warmer months will be early
morning and night time. During cooler months, muggle activity is
not too bad. On a 40 degree day, I encountered no muggles while at
the park for about 45 minutes finding a hiding spot and getting the
coords.
BTW, our house is directly accross the street to the North and my
kids play at this park quite frequently.
While the cache itself may not be all that exciting for kids (no
trade items), kids will surely enjoy the park.
Now for the actual coords:
N 101010 degrees 101011.11011110
W 1011100 degrees 11100.1000111111
