Weaver.

The preservation of the park (you know to which park we refer) is one of those grand old New York causes, like the opera or the ballet. This year’s Frederick Law Olmsted Awards Luncheon is for the ladies who do that sort of thing, with a co-chair list that reads like the Social Register and a guest list including a Rockefeller, a De Niro, a Trump, a Martha Stewart—and Avatar-let Sigourney Weaver! (Hey, she went to Chapin, so she’s in the club.) Per the organizers, 93 percent of this year’s invited residents live adjacent to the park—we’ll be looking for the seven percent contingent of Tribecans, and trying to blackmail each of them individually into giving us a prized committee seat for next year!

Central Park. Invitation only.
