I think a common "big breakfast" here is:
Eggs of some kind (over easy or scrambled, usually)
bacon or sausage
hash browns
pancakes
Then you kind of pour a lot of maple syrup on the pancakes and let it run into the sausage or bacon.
The Sugar Maple is an amazing tree.
Occasionally oatmeal, fresh fruit, or toast with jam is served. Berries are especially popular in summer since they grow abundantly in the wild here.
I'd say that's a fairly traditional upper midwest "big" breakfast. I prefer my eggs overhard, but I think scrambled is probably the most common way to serve them. My wife likes them Sunny Side Up, the "goo" makes me want to vomit.
Different here though. They do eat grits at least as far north as St.Louis. Not as common as in the south mind you and I'm pretty sure we used different toppings(I always had mine with butter and sugar...I believe salt and pepper is popular in the south), but still, I was aware of them growing up. They are on the menu at all the local Dennys and IHOPs and what have you around here as well, but I don't know anybody that eats them.
