Campground pot luck dinner?

We attended our first campground Thanksgiving dinner last weekend ( a free one, not at a resort where you pay). Other than what the owners provided which was basically a complete meal, it seemed that each camper brought a dish that would serve 8-10 people or more. I hate when you go to one(small one) and only the first 6 people in line get something and when you get there all you see is scraps left on the bowl. You should bring enough that each person can have a small serving if desired when they go thru the line. That would be less per serving that you would eat if cooking the same thing for a meal in your home. The bigger the potluck, the less you have to worry about this though.
