Great replies guys -- always wondered if they bumped it with their nose or swatted it with their tail-- sounds like nose-- the one good thing for us brookie hunters is that they tell us their location --had this happen in a lake twice as I trolled by with no hookups -- so anchored in 25' where I thought hits had happened and threw out a worm and bobber to approx. area -- no trouble catching them --so they played with the EGB but not the worms
