Sault St Marie is Canadian. Also, you might want to specify that major cities who share a name with bigger cities are excluded. Athens, Georgia is a pretty big city. Fun, though!
Thanks, my bad with Sault St. Marie. I'm not sure I understand your second point; this quiz isn't a list of all large U.S. cities. As for Athens, Georgia, see the caveat.
I personally think Birmingham Alabama is a hugely known city, as it has HUGE ties to both MLK Jr, but also to bombings and attacks during segregation and slavery times. It is arguably one of the best known US cities
