Welcome — foolish mortals — to the Abandoned Pittsburgh Haunted Gallery ... where you'll see images of Pittsburgh's industrial past illuminated by ghost lights, flashlights, and the creepiest of creaky sounds. Tricks and treats may spontaneously appear, and the spirits will sense your sympathetic vibrations and bewitch the cash register to grant you 20% off your purchase all night long. As always, admission is free. Be there, and beware!
