Between my work schedule and my wife's the food isn't apparently going to buy or cook itself

. What can I bring that I can buy at shaws on the way down? Soda, chips, maybe 5 lbs potatoe salad, plates, forks, what you need boys?
I'll see you guys at 3 pm, but I've got my brother-in-law down and he's not a big shore guy or equiped for it, so we might just have the boat in tow. Is there going to be room out back to put it John? I'd like to know before hauling it down there.
Thanks.
