Minimum height to ride: 42 inches
A rebuild of the steel indoor coaster the Golden Nugget, purchased from Morey's Piers. The ride opened as the Black Diamond in 2011, and features a coal mining theme.
I'm still shocked at how much fun this was. It has some quality theming and feels like an old school haunted house ride, which is perfect for Knoebels. 8/10
A good ride, but nothing compared to Disney, Universal, or even 6 Flags.
