The Dirty Rat
The Dirty Rat, featured in the Federation of Fly Fisher’s Pattern Encyclopaedia by Bob Lay of Montana, is a testament to simplicity and effectiveness in fly tying. This pattern, known for its unassuming appearance yet remarkable performance, has earned its place as a reliable choice for anglers year-round. Bob Lay’s design embodies the essence of what makes a successful fly: a balance of practicality and allure that entices even the most discerning of fish.
