One time I was looking for a cache listed as a reglular size container for over 2 hours. I saw nothing unusual at the GZ and when I was about to leave I took my anger out on a stump. Once I kicked it over, There was the cache... right inside the stump. I don't know why I didn't find the massive cut up tree stump as unusual for being in the middle of the woods. I guess this really wasn't luck sense it took over 2 hours to find... Whatever...
