Might be redundant but...what do you guys do with beach photography?

So, I want to do some beach photography. While. yes I consider myself a photographer. I am curious what do you guys do if you take any type of dslr camera? Do you wrap it in a plastic bag? Or use a towel to keep some areas free from loose sand? I just know it can be a worryisome thing for some and at the expense of looking like an idiot (I don't care) but... Whats's the best advice you got?
