This is what happens when MonkeyMan finds himself with spare time to fiddle around in his garage. So far his favorite thing about caching has been the excuse it gives him to buy and use tools he's never had a good reason to own before. *laughs*
Normally, I shake my head at him and say "Silly Monkey, tricks are for kids!" but when he showed me this design I was amazed and said "You are a Tricky Monkey!" He claims that this is his response to all the impressive evil hides we've discovered....and that is how the cache got its name.*grins* The symmetry was my idea! 
You may want to be careful not to toss anything carelessly around. As always, please be respectful of the area and try to leave things just as you found them!! Thanks and Enjoy! *smiles* ~TeXaN CHicK
