Learn about life as an inmate at the Missouri State Pen
Sign up for a tour of one of America's biggest and bloodiest prisons. See the conditions prisoners lived in, and learn about prison politics, inmates' pets, and famous escapees like James Earl Ray, who rode out of the penitentiary undetected in a bread truck. The tour ends in the gas chamber, where the especially macabre can pose for pictures.
Would-be ghost hunters can opt for a paranormal tour, an overnight experience, or even a class in how to recognize and record paranormal activity.
This 1836 prison is unsurprisingly, far from handicap accessible. Visitors are advised to wear comfortable clothes and shoes, and must sign a waiver before they're allowed to begin the tour. Reasonably priced souvenirs made by prisoners are available in the gift shop.
