NEW YORK (AP) — Five thousand people dressed in white got together for the world's largest popup picnic — at a Manhattan location that was revealed only at the last moment.

Guests for Tuesday's Diner en Blanc (dee-NEH' ahn BLAHN) — French for "dinner in white" — showed up at one of 24 designated city spots where the secret venue was disclosed.

Then came the spectacle: dining and dancing under the open sky at Pier 26 on the Hudson River in the toney Tribeca neighborhood. Participants brought what they wanted for a chic picnic, including food, tables, chairs and even silverware and candles. They'll also have to clean up after themselves.

The phenomenon started in Paris in 1988 and has expanded to 60 cities on five continents. More than 125,000 people signed up this year.
