Another thing, though not really interesting. Bring lots of fruit. delicious, hydrating, and the cores/peels are biodegradeable, so you con't have to haul as much garbage out.
My foodstuff normally has a base of potatoes, onions, peppers, fruits, veggies, salt pepper, butter, tortillas, salty snacks, and as much beef jerky as I can afford to bring with (I don't make my own, so it's rather expensive).
Add to that whatever meats (sausages, burger, bacon, etc.)
I'm actually going on my annual birthday camping weekend next thursday. I'm bringing my smoker/grill this time
