Back about 45 years or so ago I got into a hatch right at dark on the FFO section of the West Branch of the Octararo in southern Lancaster County. I only had two kinds of dry flies with me - light ones and dark ones. Many years later I realized that I hit a really good sulphur hatch at dark that night - I honestly didn’t even know what a sulphur was back then. I fished till I lost all of my light colored dry flies that night - either on fish or in the brush. I remember catching 21 trout that evening on my Shakespeare Wonderrod before I ran out of flies. Those memories just kind of stick with you, not bad for an inexperienced fly fishing punk way back in the day!
