THE CACHE IS NOT HIDDEN AT THE POSTED COORDINATES. THERE IS NO NEED TO GO THERE (AT LEAST AS RELATED TO FINDING THIS CACHE).
The original ammo can cache container was replaced on 3/8/2014 with a small pill bottle attached to the tree at GZ. The lid of the cache container is attached to the tree so please simply unscrew the base to access the log sheet. A spolier hint is shown in the gallery!
I have grown fond of unique puzzle caches that require finding someone or something that is/was always on the move. I've always called that "Cyber-Stalking" and enjoy how it didn't require some goofy keyword or goofy decryption methodology in order to get the final coordinates and location of the mystery cache.
Finding this cache will require that you incorporate some of the same mystery/puzzle solving tactics that you may have used if you found the caches mentioned below.
For some of you the search will be quick and easy and require one relatively simple tool. For others you may think you need to search the source code and look for hidden messages and maybe even find some red herrings along the way. Or maybe you won't and honestly will not have a clue on how to find the solution.
But I will say to everyone out there, the solution can be found, and it is out there! There is NO NEED to leave your computer to find the solution, in fact there's no need to even leave geocaching.com either!! THINK CYBER-STALKING and just keep trying and keep talking about it as I'm sure word will soon be out as to where you can find the solution!
Keep in mind though, as mentioned above, there is no need to go to the posted coordinates for any help! Though the park may be fun for the kids, stalking them (or anyone for that matter) and its consequences might not be fun and IS DEFINITELY NOT RECOMMENDED!!
If you'd like to start thinking toward the solution, again think cyber-stalking, and try to remember what it was like to find the below mystery caches.
Thanks to the respective COs, of the below caches, for their creativity in those hides. Remember the caches below significantly influenced this hide!
