I have done the impossible - found an unplotted cache! Here's the story:
I initially missed GZ of Tools of the Trade II, my coordinates had be about 20 meters North. I saw some yellow flagging off to the NE into the trees and investigated but it didn't look like the right spot. As I searched a couple came down the path so I headed back South through the trees and came across a really neat old, big, hollow popular tree. I checked it out and looking through one of the sections I saw the round silhouette of a peanut butter jar. I pulled out the cache and found that I was the first to find, the CO was abcpatricia, and it was planted October 9, 2010. I signed the log and took some pictures. I went back to the path and almost immediately spotted the flagging tape of Tools of the Trade II about 30 meters away which I enjoyed retrieving.
I suspect this mystery cache was planted but then not allowed because it was too close to the solution of Tools but the cache owner never relocated. I've e-mailed abcpatricia (the original cache owner) but had no response.
I have done what I have only dreamed of: found a cache un-looked for, found a cache that is not even marked, and I was the FTF.
