Legend has it that a Atlantic salmon fisherman was perched above a big pool and watched a fish rise, and inhale (pun intended) a cigarette as a sort "dry fly". I'm sure it was tasty... Apparently this got the old codger's brain a spinning, and poof the "butt" fly was born. I have no idea if this story is true, but I do know the people at Westwater Products manufacture and sell a ton of these tightly spun deerhair flies. What do you think? True story, urban myth, or just a great marketing idea?
