Why Dark Rides Scare the Pants Off Us

When the mysterious amusement-park attractions known as 'dark rides' were first introduced in the 1920s, they freaked people out simply by putting them on little railcars, running them through a curvy track in a dark building, and setting off manual sound effects. In the 1960s, rides like Spook-A-Rama and Whacky Shack got breathing,'' moving latex figures and trippy psychedelic illusions.

Now, these cheap thrills are getting harder and harder to come by. Collectors Weekly finds out why.
