The remaining old timer I can think of that may qualify is Lefty
Kreh. Anyone else ?
Remember names Like Ted Trueblood, Joe Brooks, Lee Wulff, Ernest Schwiebert who were the overall flyfishing icons of from the sixties onward. Perhaps Vince Marinaro also is in that class but he was mainly trout fishing as I recall. All of the rest did all of the fly fishing venues. trout, salmon, salt water, etc.. It became their profession and passion.
"The Beach Ninjy" I am not familiar with.
