I have just attended my second year at the Idaho2Fly Derby near Boise, Idaho. This year I came prepared with a secret fly called the Morrish Mouse. At last year's Derby I had one Morrish Mouse in my box and I tied it to my setup and hammered the fish, until I lost it. This year I wasn't going to make the same mistake and I came prepared with several Morrish patterns. This year the Morrish Mouse worked so well I was able to get first place in the competition. Idaho2Fly is a nonprofit organization that uses fly fishing to support men with cancer. To learn more click here.
