Where is the largest Halloween parade held in the USA?

The Village Halloween Parade is an annual holiday parade on the night of every Halloween in the Greenwich Village neighborhood of New York City. The parade, initiated in 1974 by Greenwich Village puppeteer and mask maker Ralph Lee, is the world's largest Halloween parade and the only major nighttime parade in the United States. The parade reports itself to have 50,000 costumed participants and 2 million spectators.

The Village Halloween Parade has been called "New York's Carnival." A parade is largely a spontaneous event as individual marchers can just show up in costume at the starting point without registering or paying anything. The parade's signature features include its large puppets which are animated by hundreds of volunteers. The theme each year is applied to the puppets. In addition to the puppets, more than 50 marching bands participate each year. In addition, there are some commercial Halloween parade floats.
