Anderson native Benjamin Nagengast comes by his bent for entrepreneurism and artistic design naturally. His mother founded a prominent design and engineering firm in the Anderson area, and his father was involved in several enterprises, including his own ceramic pottery business. When Ben was 10, his mother suggested the family start a pumpkin patch on their 75-acre farm. The lessons learned there helped Ben start an enterprise at the age of 13 that would become White River Paintball. Eleven years later, in 2010, he co-launched the haunted house attraction Indy Scream Park, also in the Anderson area.   Ben and his wife, Mariah Nagengast, went on to create three more family-fun theme parks, all located in Dade City, Florida, a short drive east of the Tampa area. The five parks in Florida and Indiana fall under the umbrella of the entertainment development firm Point Summit. Ben is the CEO, and Mariah is the chief acquisitions and financial officer. They now live in Florida, but they still have their fingers on the pulse of the Anderson attractions and recently invested $300,000 to upgrade elements of Indy Scream Park. They also are looking at creating new attractions on land they own next to the Scream Park and paintball business. Ben and Mariah are our guests this week to explain what it takes to operate a sprawling fear factory. The Scream Park is a serious seasonal business requiring nearly 200 employees on a busy night to create a sense of impending doom—but not danger.
