(NEW YORK) — Rainbow flags and parade floats are the order of the day in New York City and in cities around the world in celebration of gay pride. Tennis legend Billie Jean King will be one of the grand marshals of New York City’s gay pride march, along with transgender advocate Tyler Ford and civil rights organization Lambda Legal. The marches commemorate the riots that erupted in response to a police raid at a New York gay bar called the Stonewall Inn in June 1969.
