Another one that gave me heartburn was Buena Vista de las Montanas. My wife and I went out looking for it four days after it was posted.  I walked  nearly a mile cross-country to the coordinates but found nothing there.  We did a few other caches  in  the nearby mountains and ended up  taking a picnic near Reavis Trailhead where we spent about an hour relaxing and enjoying the sights, sounds and smells.  When I returned home I re-read the description and became convinced that the description didn't match the location. The described elevation was about 1500 feet off and it was certainly a much farther walk than 100 feet described.  I notified the owner that his coords had to be wrong and provided the evidence I had.  He insisted they were correct.  I  asserted that they couldn't possibly be correct.  He again swore that they were.  Finally, he saw that they were in error and he posted the correct coordinates.  They coordinates turned out to be just a few hundred feet from where my wife and I had our little picnic that day.  We missed out on a first find and we haven't been back to the area since.
