I agree with you and know it's not necessary, but I'm always curious about these details nonetheless. I know a few of your Florida amigos are well aware of it first hand. I am curious about any modifiable factors involved in attacks aside from the obvious "don't go in the water" option.
Have fun and be careful doing the "Jesus walk" out your way.
It isn't necessary to have anything shiny John. Your hand makes a nice trolling teaser dragging through the water. Or, just wipeout near the sharks, they may strike very suddenly before deciding we taste bad. Going into the water off plane for an extended period around sharks has also led to problems in the past.
