The Chuck Caddis is a long-standing pattern, and remains a very effective one coast-to-coast. I first learned this pattern more than 25 years ago, and still tie and fish it faithfully.

Ralph,
Nice fly, nice video. Did you get a new camera? (out on the road for 4 weeks with little wi-fi service at the campgrounds and may have missed that).
Regards,
Scott
Yes sir…a new camera is now in use.

Scott
