I have a funny feeling that there are not actually MORE sharks than there used to be along the coasts, but that we have ways of SEEING more sharks than we used to. Sort of like tornadoes. Used to be, when almost no one lived "out there" and no one had a video camera, and there was no Doppler radar, a tornado could drop down and go wild and no one would even know. Now, though ....
These sharks, they've probably been swimming around me on Carolina beaches since I were a lad ....
