If you're worried about sharks, maybe you've picked the wrong hobby. I'm not saying be stupid about it, like paddling out into a whole school of bull sharks, or hitting up Recife in Brazil. And not saying I've got the stones of Mark Healey, or even some of the guys on this forum that can see the grey triangle and just ignore it...but the fact is the same thing that makes good breaks attracts the things sharks like to eat. If you're in shark central be aware of course, but if you're looking at a nicely breaking wave and worrying about sharks...maybe this sport isn't for you.
They may be concentrated in places like SI and New Smyrna but they are everywhere. Largest tiger shark ever caught was off the Cherry Grove pier in N Myrtle Beach, and that's not exactly a hot spot for sharks.
Relax bro - I surf in Jersey and don't have to really worry about sharks there. I was just asking for some opinions and trying to play it safe
