LA, NY Metro talk trash over Mets-Dodgers NLDS matchup

NEW YORK, NY - DECEMBER 05: People exit a subway stop in Manhattan two days after a man was pushed to his death in front of a train on December 5, 2012 in New York City. The incident was caught by a photographer and has since raised questions as to why someone didn't help the man before the train struck him. The New York City subway system, with 468 stations in operation, is the most extensive public transportation system in the world. It is also one of the world's oldest public transit systems, with the first underground line of the subway opening on October 27, 1904. (Photo by Spencer Platt/Getty Images)

Now that it's official that the Los Angeles Dodgers and New York Mets will be facing off in the NLDS, the trash talking has begun.

With the Dodgers clinching the NL West on Tuesday, Los Angeles and New York are set to square off in an East Coast-West Coast affair beginning on Oct. 9.

As the cities' transportation systems gear up for the series next week, they engaged in some banter on Wednesday, which began when Los Angeles' Metro sent a tweet to New York's MTA.
