True, my river bound buddy. If the fish aren't going for the big fast baits, downsize and slow it up.
General advice is to work the transitions, in weather, vegetation, daylight, flow, barometric pressure, lunar influence, bottom composition and depth. That's the location part. Then you get to choose your bait and its colour, action, size, depth, to somehow fool a prehistoric creature,with a brain the size of a pea, into thinking that there is food at the end of that Gamakatsu. . Pretty dang easy.
I think that barometric pressure is only one of a variety of alleged influences on your fishing success. If none of the crew caught anything, then you can seem wise by claiming the new cold front is the reason. If that's not the case, then see Para. #2.
This link is as good as any for containing the current published wisdom. Hope this hleps.
