It just gets me that these guys go diving on the W.A. coast and are surprised (and so emotional) when they see a white pointer?

IT`S THEIR FREAKIN HOME! Where are you expecting the freakin things to be? It`s not going to be on the freeway while you`re driving back from your lovely diving trip!
Last year I saw a shark (not a great white) , don`t know what it was, at Shoal water while kiting. Did take me by surprise a bit, but I didn`t freak out and think I need to tell the whole world about this strange phanomenon. I am playing in their domain. It`s as if we expect them to all go sit in a corner while we are doin our thing in the water and when they don`t it`s all so "strange" .
We know sharks are in the water, we take our chances. If you`re not comfortable with that stay out of the water and don`t try and freak everyone else out.
