My dads two favorite flys were the Muskrat and a Streamer called the Brown Bear. He had a few other patterns, but by and large as I remembered it, those were his two favorites.
So why the Brown Hackle Peacock when it wasnt one of his favorites? I was raised in Colorado. He was raised in Utah near the Provo River. When ever the discussion of fly fishing and patterns came up, he would always refer to his early years. He maintained the only fly one needed to catch huge Browns on the Provo River was, you guessed it, the BH Peacock SIZE 12.
I happen to know he always had a couple stashed away anywhere he ever fished, just in case the fish wouldnt hit one of his "favorites".

That would have taken place in the late 1930's till 1944 when he enlisted in the Marines.
