There are some caches that are very well hidden and are difficult to find. There are other caches that are either not well hidden or are hidden in such a way that an experienced geocacher will find them very quickly. Then there are those caches which are placed in obvious locations but, for one reason or another, some of us cannot see them and we either spend a great deal of time or we make repeated visits before the cry of "Eureka" and then comments like "Why did I miss that?" or "Why didn't I see that before?" or "I must have been suffering from cache blindness".
We have had so many of those cache blindness experiences that we thought a small number of caches dedicated to the phenomenon would be appropriate.
