If you’re the superstitious type, Blairstown might not be your ideal destination on Friday the 13th. But at the Blairstown Diner, the so‑called "curse" is part of the charm — and business is booming because of it.

The Warren County landmark has become a prominent site for horror fans thanks to its starring role in the iconic 1980 slasher film, "Friday the 13th." Much of the 1980 film was shot in Blairstown, and the diner remains one of the most recognizable locations.

“This is the birthplace of Jason Voorhees,” said Brian Emenheiser, of Allentown, Pennsylvania.

Every Friday the 13th, the diner transforms into a full‑scale fan convention. Visitors travel from across the region to immerse themselves in the world of Camp Crystal Lake.

“It’s Friday the 13th and it’s Valentine’s Day," says Axel Gramata, of South River, who joked that he was actually a bigger fan of "A Nightmare on Elm Street" villain Freddy Krueger.

“[Jason Voorhees has] become a beloved character…everybody loves Jason and he’s just kind of become this warm and endearing figure,” said Genoveva Rossi, of Wayne.

The diner has been hosting the themed celebration for five years. It has become more than just a business boost, but also a community event.

“The parking lot is packed…They got the Blairstown Jason walking around. They got all the movie props inside. It’s awesome,” said Jason Bradley, of Long Pond, Pennsylvania.

Even the menu gets a horror‑themed makeover.

“They always do something so cute and fun…the horror community is a wild, fun, nerdy community that I’m happy to be a part of,” said Shealyn Coniglio, of Morristown.

Fans of all ages showed up in costume, just trying to get into the spirit.

“We’re just trying to get the Jason experience…and we’re going to Camp No-Be-Bo-Sco after this, where everything was filmed,” said Elijah Lee, of Bergenfield.

And this year brings even more excitement - a new "Crystal Lake" TV series filmed in the area is expected to debut soon.

“It’s even a more special year with three 'Friday the 13ths,'” Emenheiser said.

Three chances for bad luck — or three chances to celebrate, depending on who you ask.
