My advice to friends is this: quit surfing immediately if not sooner! The threat of shark attack is REAL, and next time you are out in the ocean, know you are in THEIR domain. They come quickly without warning and devastate their prey (US). It gives me the creeps just thinking about what is under my board when i am surfing. Next time you are out and feel a tingle down your spine... Pay attention. Get out and go home where it is safe.
