My biggest ling ever came between the marina and the boat ramp, many years ago. It was 14lbs. I have found big rock piles are were these fish hang out. They may not be eating but killing minnows to protect their eggs. So if you have flags tripped and a minnow with now sacales and dead you have been linged.. These fish will lay at or around the big rocks that may be 8 feet at the top and 14 to 20 plus at the base. They will try and rap you up in rocks or other crap if they get a chance. Good luck
