As this was my first cache machine, I was more than happy to follow the route put together by Travis, so I wasn't likely to go to the "Do Not Find" caches. I cache with my phone app. As I was chauffeured to the next cache (thanks RocketGlider) on the list I read the details, hint, size and last few logs on the cache for us... If there had been a note in the log stating that a cache was "Do Not Find" for the CM, I would have seen it. Just a thought that might help some.
