Vortex Haunted House

115 W 27th St between Sixth and Seventh Aves, first floor Subway: N, R, 1 to 28th St Don a protective facemask (you have to), pick up a flashlight (you’ll want to), and venture into this dark labyrinth alone (eek!). During the terrifying 20 minutes that follow, you won’t be allowed to talk, but screaming your head off is, of course, permitted.
