Excluding New York City:
Also excluding two other hotspots, Detroit and New Orleans:

Someone in the comments makes a point about different rates of testing -- it doesn't seem possible to link to it:
The second paragraph explains why there might be more cases in cities, especially dense cities like NYC, but I don't see how the first paragraph changes the overall picture. Granted that the cities have seen more testing and therefore more cases...but if the rest of the country (excluding NYC, etc) had the same testing rate as NYC etc they'd see more cases too. Maybe not more at the same proportion, but more. So it's not obvious to me the second graph can be easily explained away.
