Secret Mausoleum Club
Time Out says
Adventure society Atlas Obscura invites you to enter the historic Green-Wood Cemetery for a night of mysterious performances and candelit surprises. Take a midnight spin through the grounds, where you’ll use clues from beyond the grave to decipher the night’s fabulously baroque theme. Plan a date that plays to your dark side, or go solo to make new friends. Sea Witch Tavern provides an open bar and after-party, so there are plenty of chances to socialize among the living and the dead.
