Which coaster has the world's longest initial drop tunnel and where is it located?

The correct answer relates to the coaster with the world's longest initial drop tunnel, which is known for its impressive design and the thrill it provides to riders. Gold Striker, located at California's Great America, features an initial drop that is not only steep and extreme but also incorporates a tunnel that enhances the experience by adding an element of surprise and acceleration as riders rush through the dark. This unique characteristic sets it apart from other coasters, making it a standout attraction for enthusiasts seeking exhilarating experiences.

The other coasters listed, such as Fury 325 and Steel Vengeance at Cedar Point, while highly regarded and known for their thrilling designs and drop heights, do not feature the same record-setting initial drop tunnel that defines Gold Striker's appeal. Millennium Force, another iconic coaster at Cedar Point known for its height and speed, similarly lacks the long initial drop tunnel aspect that Gold Striker boasts. Hence, the notable feature of Gold Striker makes it the correct answer in this context.
