I agree with that.
I used to love stalking along the margins but on a lot of the waters I've fished in the last 10 years I've tended not to find carp close in to fish for. I'm sure this is due to modern 'anglers' making a racket on the bank - setting up right on the waters edge, having bbq's, with those God awful ridgemonkey lights lighting up the bivvy like a space station.
I'd used to always have one rod in the margins by default and for my first 10 years angling that was normally the most productive rod. I don't do that anymore - they usually sit motionless for 2 days now. I'd have to see feeding carp to pop one in the margins these days, which is rare.
Nowadays I'll go stalking only to do three laps, find nothing, and end up back in the swim chucking zigs at open water where the fish are showing.
Wouldn't it lol
