Mark Cuban's biggest 'Shark Tank' investment of all time was in this spooky Halloween event - here's what it's like

The Haunted Hayride has been a popular Halloween attraction in Los Angeles for seven years. Taking place in Griffith Park, it typically brings in about 65,000 people over its 17-night run, and tickets almost always sell out.

In 2013, Mark Cuban made his biggest investment in "Shark Tank" history when he gave $2 million to Ten Thirty One Productions, the company that produces the spooky event.

CEO Melissa Carbone wants the Haunted Hayride to become a household name and a new Halloween tradition for people across the country.

"The ultimate long-term goal is to have a Ten Thirty One attraction in every major metropolitan area in the United States," she told Business Insider in a 2014 interview.

This year, they checked a big goal off that list by bringing the experience to New York City. We went to see how scary it really was.
