Got a question for the board. I go up to Denison Dam fairly often and wade fish the Oklahoma side, but I am always fly fishing so I leave as soon as they start releasing water so I don't drown. I always see people on the Texas side throwing surf rods down past the power lines, but I have no idea what they are fishing with. It appears they are throwing something that resembles a saltwater popping cork, but they just cast it and reel it back in at a pretty good rate of speed so they are not treating it as a popping cork. All I know is the rig makes a giant splash when it hits the water and I don't see them catching anything most of the time. How does this rig work and what are they dropping behind the thing that is not a popping cork? Thanks.
