The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
"He was rude, boorish, condescending (assumed I was a rank beginner when I have actually been throwing flies for over 25 years), overbearing (I couldn't hardly get a word in edgewise), insulted my choice of tackle, etc."
That sounds like many of the guys I run into on the rivers I fish.
