In my time trapping bait In Md and Pa through the years in late fall you will find minnows and chubs in the deepest holes you can find,They will move into warm open flats in a creek or stream on a mild day,but for the most part they will stay deep around structure like root balls and tucked into a hole in the washout areas.You might get a trap or two stuck once in a while but the best bait comes from places like these..ps: Suckers seem to like the same places,anywhere there's a hole and a current break.Hope this helps some...Slabhappy56
