The cache is at the posted coordinates.
This is a Challenge Cache so you must meet the qualifications before you can claim a "Found It." To claim a find for this cache, you must have found at least 18 caches with unique Difficulty/Terrain combinations of the 81 possible, utilizing only "Wherigo" types. The "3.5" difficulty level is a reflection of the difficulty in finding the Wherigo caches required rather than the actual "1.0" difficulty of finding this particular cache. As of the published date, my Wherigo D/T combo count is 23 as shown below:
One of the oldest types of geocaching challenges is to complete the difficulty/terrain (D/T) grid displayed on your Statistics page. The D/T grid is often referred to as the "Fizzy Grid" after the first challenge of this type, GC11E8N in California. This is an easier variant of that challenge as you merely need to fill ANY 18 of the 81 possible D/T squares, but to log it as a "Found It," you must do so using only the "Wherigo" type caches.
There are five additional "18/81" Fizzy Challenge Caches, each within about a couple of kilometers from GZ:
GC7JEHN - "Traditional" Fizzy Challenge: 18/81
GC7JM8P - "Multi" Fizzy Challenge: 18/81
GC7JMDV - "Unknown" Fizzy Challenge: 18/81
GC96FV5 - "Earthcache" Fizzy Challenge: 18/81
GC9WXY8 - "Letterbox Fizzy Challenge: 18/81
A couple of other local Saskatoon area variations of the Fizzy Grid challenge are:
Nirakmit's Evil Challenge - GC1EMAC, (5 X 5)
Double Fizzy Challenge GC6TYGR, (5 X 1.5)
To show that you do indeed qualify, please attach either a copy of the results of your Challenge Checker Query, or a listing of your 18 qualifying finds. A "Write Note" log may be utilized for those who find it prior to qualifying, or as an interim measure for those who wish to log it prior to attaching the required qualification information.
You'll need to bring your own pen or pencil. Enjoy your quest!
