Vanessa,
I'm from Massachusetts - about as "Yankee" as it gets - and our Thanksgiving dinners were always HUGE. Turkey, at least one kind of stuffing, sweet potatoes, mashed potatoes, gravy, 4 or 5 kinds of vegetables, rolls, salad, both kinds of cranberry sauce, macaroni and cheese, and several desserts.
We live in Virginia now and I typically make Turkey, stuffing, gravy, potatoes, corn casserole, rolls and cheesecake (although I forgot the rolls this year). But that's only because there are only four of us and it would be crazy to make a ton of food that most of my family wouldn't eat anyway because they don't like vegetables.
Kinda funny that we're having a "Yankee" Thanksgiving dinner in Virginia and didn't when I was growing up in Mass.
