they can stack up like cord wood and drive you crazy . I am betting there is a bite "window" on the ones that wont bite and when the window opens its about on fire till it slams shut . I see winter fish do this over and over on several locations and have no clue why but to be sure if you find that "window" hit it every day till it changes time zones and stock the freezer .
that there is for sure what you got ….I think maybe ...you know could be ….possibly ...
