History
In March 2007, ZDT's Amusement Park first opened its doors to the public and featured five indoor attractions. Owners Danny and Sarah Donhauser named the park after their three children – Zac, Danielle, and Tiffany – using the first letter of each child's name. Multi-level go-karts were added in 2008, and Mad Raft Water Coaster, a water coaster and the park's first water ride, opened in 2011.[citation needed] The Switchback roller coaster was added in 2015.
The park ceased operations on August 17, 2025 due to rising costs.[1][2]

Switchback
In late 2014, ZDT's unveiled plans to build Switchback, a custom hybrid wooden shuttle roller coaster that featured a 104-degree overbanked turn and an 87-degree incline (a world record in wooden coaster angles of descent).[3] Manufactured by The Gravity Group, the 63-foot-tall (19 m) ride dropped riders 58 feet (18 m) and reached speeds of up to 40 mph (64 km/h).[4] The roller coaster opened to the public on October 17, 2015.[4] It navigated through and around various buildings and structures in the park before reaching a culminating element called the "Grand Spike", which sent riders up an 87-degree incline.[3] Switchback was the first and only wooden shuttle coaster of its kind, and derived its name from the 1884 Switchback Railway, the first true roller coaster in United States.[5][6][7]
