Sorry about...Guy hit it right on the button! tongue2laminac. Ok Puke lines are not a scientific term it is where the current or wind current makes a line near eddies or a wind line that you can see. There will be small to large woody debris, aquatic vegetation, bugs, and plankton, fir and pine needles and what ever else that was floating around on the body of water that your fishing all get collected in a line, under those there will be fish feasting on the bounty of goodies that are drifting around.
