The official lighting of the greatly diminished Grand Army Plaza display (which is what is left of last year’s wonderful Prospect Park in Lights decorations) is happening tonight. The festivities start at 5:30 PM. Per the official release: “Mayor Michael R. Bloomberg invites you to celebrate the holiday season in Brooklyn and to turn on the lights! Festive live entertainment and hot chocolate will make the season bright. Rain or shine, the lights will go on. Please join us.” Well, at least, the remaining lights will go on.
