a couple of years ago, i was fishing Presidents day weekend. Fished on Friday came back Saturday morning and there were coyote tracks near every hole we drilled the day before. Fished again on Sunday and there was more coyote tracks checking out the holes from the previous day. I am guessing after we left the coyote would come out on the ice and check for anything was left around the holes. This would be a good tactic for a money hunt.
