Full disclosure: The hardworking staff grew up in Manhattan, but we’ve lived in Boston for the past 42 years. So we can’t help noticing the yin and yang of the two cities.

Latest example: The Billy Joel concert index.

Yesterday’s Boston Globe featured this American Express/Fenway Park full-page ad.

Then again, yesterday’s New York Times featured this Citi/Madison Square Garden counterpart.

Not judging. Just saying.
