This spring I took a trip to Yellow Creek in Bedford County, PA. I caught this one particular brown trout that had spectacular blue spots. I had never really noticed these before on brown trout. Since then, I notice this feature all the time – it seems relatively commonplace. Why did I notice these blue spots on that fish, when I’d probably seen them a hundred times before, on a hundred other fish? I don’t have the answer. I don’t know if it reflects only on me or on human nature in general. But, apparently my power to ignore what’s right in front of me can be impressive. What else haven’t I noticed?
