Whatever you do, do not leave anything of value around unless you have someone you trust to watch it. A few years ago a guy sitting about ten feet from me had all of his stuff stolen because he fell asleep (the only people that were around were those passing out the numerous flyers to clubs so I'm sure it was them.) In fact, try not to bring anything of real value to the beach, just some money and maybe one credit card well hidden.

If you want to take pictures, return to the beach later to take them. I do take my Iphone with me but keep the actual phone out of view (although I'm listening to music.) I would never leave it alone.

Glad to hear you are not a big drinker. Along with the 200 pound guy that is burnt red from the sun, and wearing black tube socks and bermuda shorts, nothing attracts the thieves more than a drunk unaware of his surroundings.
