The Yankees have that strength, and almost all of them are Yankee fans in new york.

In a comic book about new york people, the author once told people who had just arrived in new york: "If you want to make friends with new york people, tell them that you are a diehard Yankee fan."

New york is also the largest financial center in the United States, so there are quite a few billionaires and superstars, so their wearing has also caused a craze for NY hats among many citizens.
