I sure did. There was a cache that was painfully close to where I lived that I simply couldn't find. I would walk my dog past GZ all the time and never be able to find it. I tried different GPS apps on my phone (the coordinates had me in the middle of the road), brought other NOOBS along (not real helpful) and even tried to PAF (phone a friend - he told me I was thinking too hard - huh?), without any luck.
Then one day I was searching for a similar cache in another city and found an evil little cranny (look it up:) I had never noticed before, and a light bulb went on.
I could not wait to get home.
VICTORY!!!
If you have a nemesis cache that you remember as a NOOB, hide one like it and use the same title - but change the CAM to your cache.
