This New Yorker article chronicles haunted houses that utilize smells in strange and disturbing ways.
Some excerpts:
New Yorker Quote of the Day: "Egner’s personal favorite
haunted scent experience was another bait-and-switch scene: as visitors
approached a dimly lit table, they could smell roast turkey, mashed potatoes,
and stuffing, and see dishes piled high with food—which turned out, on closer
inspection, to be cured hog guts and other viscera. 'I’m sure that we ruined
somebody’s Thanksgiving that year,' Egner told me gleefully."
But the only time that a smell has been toned down midseason
was this year—and it was for the benefit of the staff rather than the visitors.
“There’s a really strong cat-urine smell this year, and it is really sticking
with us,” Egner said. “Our clothes, our hair … I have a dog, and he is very
confused when I get home.”
