Many years ago an article appeared somewhere (Esquire, Fly Fisherman I
don't know where)
that was the story of an accidental evesdropping on a 'famous
fisherman'

The writer had a guest invitation to spend the day fishing at an
exclusive Long Island
fishing club. He went into the bushes to pee, and on his way back,
while peering through
the bushes, he recognized a 'famous fly fishing writer' working over
the pool he had
just left. He succombed to temptation and surreptiously watched this
famous fisherman
from afar, for several hours....until the end of the day, in fact.

The punchline came the following day, when the writer read the club's
fishing logs.
The famous fisherman had entered into the log that he'd caught over 30
fish.
But the writer had watched him all day, and knew he had caught only a
half a dozen or so.

I'd like to find a copy or a reprint of that article. I read it once,
so long ago I no longer
remember who wrote it or who published it. Help me out if you can.
