The most difficult time I had finding a micro was in 'The Green Monster', located in Edmonds, Washington. The cache is a small bison tube located INSIDE a mature hedge that borders a sport field. No matter how sunny it was outside, once inside the monster, it was too dark to see. The nagging frustration that I felt while searching for it was eventually replaced with a burst of satisfaction when I finally did find it. I've dropped the evil micro coin in 'Land of the Gnomes', the closest cache to the 'Green Monster'.
