Very enlightening. I'm sorry to hear of his demise.

I own the vhs and dvd versions of this movie. I always was under the impression that was Mr. McLean in that wonderful scene. I recall my girl friend at the time, when we saw it in the theater, asking me what is that knot (she was and is quite the fly fisherwoman). I told her I thought it was a turle knot. I've always meant to give it a try......never have.
By the way, she immediately identified the fly that struck the older brother in back of the neck as a large stonefly.
She was and is pretty savvy!

Ah, memories!
