This is an interview with a legend of fly tying and fishing the dry fly in Upstate New York. Albert Daher asks Del how he came about discovering the origins of the Catskill Dry Fly. Del made a video of how to tye the patters that made a new Renaissance in fly fishing for trout. It is available at The Catskill Fly Fishing Center and Museum.
