True enough. When the fish there are keyed in on a hatch, even a canoe
floating directly over them only puts them down for a minute or so. A
bird flying low over the water will spook them, but not for long. They
are simply too used to people being around, thus the success of the
technique you described. If that is the same lady I think it was, she
caught a 23" brown in there about a month ago.
