Rye- sometimes the baits are out that far. Other times they get dropped just behind the breakers, and can be anywhere in between. I would say most of ours are anywhere from 200-600 yards though. Big reels filled with braid allow us to fish that far if the weather permits, which is nice for the days when the mud line is sitting there 300 yards out, and nothing but clear water beyond it.
still, think about how many shark attacks you hear of in NC. Then think of the number guys fishing seriously fishing them. Couple that with all the other stuff a shark will eat such as dumped by-catch from the trawlers, schools of rays, and whatever else, and I think you'll see that a fishermans baits are not likely to attract any more sharks than whats out there. Ive yet to have anyone come up and give me the 'what for' for sharking. Mostly its people that are curious and like to listen to the stories of out catches.
