According to legend, the fire goddess Pele and a hog-faced demigod named Kamapua’a had a star-crossed love affair. The lovers were elemental opposites: Pele’s lava flows brought flame and destruction, while Kamapua’a restored rain, vegetation, and animal life. Ultimately they decided to part forever, with Pele claiming one side of Oahu for fire and Kamapua’a retreating to the other side, where all is wet and lush. Today, Hawaiian motorists are careful never to drive with pork in their car along the old Pali highway, which crosses Oahu. According to legend, carrying pork—representing hog-faced Kamapua’a—over to Pele’s side of the island will enrage her spirit, and she will get her revenge by making the car stall until the driver throws the pork out the window.

When it comes to abandoned buildings, penitentiaries might rank only slightly behind psychiatric hospitals in creep factor—and the Old Idaho Penitentiary, with its built-in gallows and death row, may be one of the country's creepiest. Between 1872 and 1973, the Boise prison served as a temporary home to more than 13,000 prisoners—including Raymond Allen Snowden, a.k.a. "Idaho's Jack the Ripper." Some believe he still haunts what is known as 5 House, where the prison's gallows were located. On October 18, 1957, Snowden was brought here to be executed, but the noose that should have broken his neck didn't; it took 15 minutes for him to suffocate. In the years since, visitors to the "Old Pen" have reported strange happenings in 5 House and other areas of the former prison, such as hearing odd sounds and voices and being overcome by strong feelings of sadness. The prison is open to the public year-round for paranormal enthusiasts who want to test their mettle.

In the depths of the Great Depression, the Oh Henry Ballroom southwest of Chicago drew young people hoping to dance away their troubles. One night, a teenage girl named Mary had a fight with her boyfriend at a dance and decided to walk home along Archer Avenue. She was killed by a hit-and-run driver and buried nearby in Resurrection Cemetery. Since then, residents have described a girl in a white party dress hitchhiking along the avenue. A cab driver even picked her up, and she asked to be taken to the cemetery. But by the time they arrived at the gates, Resurrection Mary had vanished.
