Futzer's Cadfly in Coldwater Species Posted October 5, 2008 · Report reply Do not worry, I am full of useless information and patterns. I may just submit a few for the swaps and contests. Cheers and tight lines, Futzer. PS. I forgot to add I developed this in 1985 on the Blue river between Dillion res. and Green Mtn Res. in Colorado. And thank you for the nice comments!
