When I travel if I were to say I'm from Ontario, many wouldn't know where that is, but saying Canada they would. And guess what my friend, Canada is the 3rd largest country in the world!!!! And yes the "culture" between the east coast and west coast and Ontario and Quebec are drastically different too.

Yep, I've spent time in all of the states. People from Louisiana are less like people in Oregon than people in Germany are like people in France. The cultural differences are notable. Accents differ. Morality and beliefs differ. The United states is exactly what it's called. Multiple states with differing people, cultures, and laws which are United.
