Fly fishing looks like fishing, but devotees will tell you it's something closer to a moving meditation with a tackle box. This week we wade into the world of hand-tied flies, river reading, and the particular breed of person who happily spends three hours casting without catching a single thing — and considers it a perfect morning. From the Victorian origins of chalk stream fishing to the cult of the fly tying desk, we explore why this hobby is less about the fish and almost entirely about the act of paying attention.
