welcome to mallory square

If you've ever seen one of those ceremonies where the mayor of a city gives some notorious notable the "key to the city", haven't you ever wondered how the key recipient knows which doorway to the city the key fits?
Like in New York. . . is it for the Lincoln Tunnel, the Holland Tunnel or the GWB (George Washington Bridge)?

If you get awarded the "key to the city" of Key West, there is no doubt, Mallory Square is your way in.
