I "get" the point, but there are some oddities in the cities chosen.
On the West Coast, Seattle and Portland are noticeable omissions. In CA, LA is a natural choice, being the largest city in CA, but SF is only the 4th largest; what about San Diego and San Jose, the 2nd and 3rd largest CA cities?
Mesa, AZ's 3rd largest city, is shown, but not Phoenix and Tucson, the largest and 2nd largest?
Colorado Springs is shown but not Denver? Dallas is shown but not Houston? Neither KC nor St. Louis are shown? Detroit? Philadelphia? Savannah?
I would not at all be surprised if including those cities confirmed and emphasized the pattern, but omissions that obvious create an appearance of selectivity.
