I fished today for about an hour at a small lake across the street from my house. The third fly I tied on was a simple, black boa yarn leech. I have fished this fly before and did well so the "thank you" is long overdue. I caught some big spunky bluegill and several bass. It's a simple, yet productive, fly, and wanted to give Rick kudos for sharing the fly and the instructions on tying it ( you can find them in the archives).
