Indiana woman Diamondback’s 20 millionth rider

A woman from Seymour, Indiana traveled to Kings Island to become the 20 millionth rider to board the Diamondback roller coaster at Kings Island Wednesday night.

Grace Timmons, 23, was given a souvenir package that included a Diamondback hat, coaster cutout and poster; Eiffel Tower coaster cutout; Kings Island signpost magnet set and a large sign proclaimer her as the milestone rider.

"I for sure thought I was being pranked. I was looking for cameras, because I thought I was being pranked," Timmons said. "I'm the happiest I could ever be, honestly."

Diamondback debuted in 2009. The ride stands 230 feet at its highest point with a first drop of 215 at a 74-degree angle.

Riders snake their way around 5,282 feet of steel track at speeds up to 80 mph.

Only two other roller coasters have reached the 20 million rider mark faster in the park’s 50-year history: The Racer and Vortex.
