(N.Y. POST) It’s the Big Apple’s newest — and goriest — tourist attraction.

Visitors flocked to Seventh Avenue between 37th and 38th streets yesterday to take pictures of each other standing next to bloodstains on the sidewalk — left by the knife-wielding madman shot dead by cops a day earlier.

“It’s amazing. It’s like, ‘Oh, my God!’ That’s so different than what we’re used to. It’s so gross,” said Abby Smith, 25, of the Scottish city of Edinburgh, which averages fewer than a dozen murders a year.

Smith giddily snapped photo after photo of her traveling pal, Scott Ramsey, standing over the blood to show the folks back home.
