That's curious. Stranger still, and brutally weird, is the location of the party: Pacific Street between Carlton and Vanderbilt avenues in the AY footprint, opposite the under-demolition Ward Bakery, where a stop-work order exists and where the handful of residents left are, as far as I know, plaintiffs in the eminent domain case or their relatives. As Develop Don't Destroy Brooklyn comments, "Call us crazy but we thought block parties were thrown by PEOPLE LIVING ON THE BLOCK."
In other words, the "community" celebration is on a block scheduled for Phase 2 of the project, without start date or deadline, threatened by "condemnation blight." (And, as I've been reminded, the block will be demapped for the project, so it won't exist.) An email informs us that the organizer is Delia Hunley-Adossa, who also MC'd the strained "Brooklyn Day" rally.
