Some questions simply cannot be answered by mortal man: Why do fools fall in love? Should I stay or should I go? But I digress. Consider Leisenring’s Gray Hackle. Why would you specify “yellow or white creamy furnace hackle” and then name the fly…well, you can see where this is going. Maybe Big Jim’s stash of said hackle had a gray cast to it. Maybe it looked a certain way when wet. We may never know. But we do know that there’s a little magic in this design. See for yourself.
