Numbers: Fizzy Challenge Mystery Cache

The coordinates for this cache IS at the posted location. BUT, in order to log this as a find, you must complete the challenge. Play nice and only search for, sign, and log this AFTER you have done so.

I really love Challenge Caches.  Here's another familiar one for you to attempt. This one is not very easy to qualify for.  

IN ORDER TO LOG THIS CACHE AS A FIND, YOU MUST COMPLETE YOUR FIZZY GRID. The Fizzy grid will be filled when you have found at least one geocache in combination of your Difficulty/Terrain grid.  I can check your public statistics to verify that you qualify for this challenge.  Once you have met the requirements, go find it and sign the log. The Difficulty and Terrain for this cache are a factor of the effort you will have to put into qualifying for the cache.
