Which two American cities are much more similar than most people realize?

E.g., after spending a week in New Orleans, I was struck by how much the city reminded me of Philadelphia with palm trees. Both have very rich historic districts, iconic local foods (cheesesteaks and po boys), a mix of beauty and grit where vibrant neighborhoods exist alongside significant portion of the city facing hardship, the attitudes of the residents felt similar, etc.

What are two other cities that are geographically far apart but share a similar sense of familiarity?
