I'll never understand trout 
Many many moons ago I started trout fishing on Walthamstow Reservoirs.
One very slow day, the chap that issued the tickets came down to see how us kids were getting on.
On hearing we had not caught a thing, he took my rod, cast maybe 5-6 yards, and proceeded to rip the line out the water, cast, rip, cast and so on for a minute or so, whilst looking at us with a grin on his face.
He then handed me the rod, and said, "Cast out and let the fly sink, dont move it, just leave it to sink".
10 seconds later I was into my first trout, as was my mate.
He reckoned the stockies heard the line ripping the surface and to them it sounded like feed pellets being shovelled into the water, so it was like a dinner bell to them.
Not suggesting your trout are mere stockies...but I wonder if there is a bit of Pavlovs Dogs going on with any fishery reard residents??
