The date 03/14 is a special day, it is the inofficial
"celebration day" of the number "Pi" (p=3.14....)
There will be geocaching
events taking place all over the world this day.
The Spanish geocaching association (G.E.A) is uniting as many as
possible of these events under the motto "United
Pi2009".
The organizers of these events will hide one traditional cache
and one unknown cache each where the later only can be found if the
traditional cache is found first.
There are codes hidden in all the traditional caches worldwide
which you need for solving the formula you are given. The formula
will then result in the coordinates for the unknown cache.
In order to find the unknown cache in your vicinity you need the
numbers found in the traditional caches published in the other
events listed below. You can receive these numbers by contacting
other geocachers who found the United PI2009 caches in their own
vicinity and then exchange your number with their found number.
Every geocacher is only allowed to exchange the number which he
has found in a cache himself, not numbers that he has got by
exchanging with others !!
Once you have found and logged your local UnitedPI2009 traditional
cache on www.geocaching.com you may be contacted by other
geocachers who want to receive or exchange the number which you
have found.
Be polite and helpful to your geocaching colleagues !
