On the 29th of April, 1972, Kings Island amusement park in Mason, Ohio, opened for business. The 364-acre amusement park included a $2 million dark ride, a record-breaking rollercoaster, and numerous other entertainments and attractions. It was a hit. Within just a few years the park saw visitor numbers in the millions, and was known not just across the state, but nationwide. Little spoken of, however, were several bizarre freak accidents that took place within the park in subsequent years, and which cost several staff and guests their lives.
