People are not taught to hunt ruffed grouse using the same techniques modern fishermen use. But in a lake, different times of year, the fish are in different places, different times of day they are in different places. Different times of day their behavior is different. Weather plays a role.
Use your brain to eliminate the parts of the lake that are dead water.
Think of the forest as square lakes. Use topography like a lake bottom map. Eliminate dead water.
It's weird, because we expect to fish as I described, yet we refuse to teach hunting that way.
