Come up with a creative team name and join the Grand Central Scramble Family Scavenger Hunt. To win, you’ll have to go nuts in the Whispering Gallery, spot surprises in the stars in the “sky,” find TV celebs in the fabulous food court, stand on fish under an upside-down tree in the Grand Central Market, learn the arrival time of a “ghost” train, count creepy critters trying to invade a “ship,” and find funny details in the latest exhibit inside the Transit Museum Gallery, to name just a few hunt highlights.
