Couple weeks ago i was fishing fromm the bank and was using goldfish and nightcrawlers. I was using slip bobbers and fishing the bottom. Every time i would reel in mine line to re-cast the worms would be gone. So I tired one worm, same thing, i ri 3 at a time and same thing happened every time. Not once did I see the bobber move so i dont think it was a fish taking it. Maybe it was the current?? any ideas?
