Kings Island’s sold-out Coasterstock includes hundreds of roller coaster enthusiasts

Those who attend the sold-out event are riding Orion, which reaches up to 91 miles per hour, and The Beast, among other rides. They also are enjoying nighttime rides, Helbig said.

Enthusiasts also get behind-the-scenes tours of roller coasters and other Kings Island attractions. They will have question and answer time with park staff and coaster designers, and this year they will have a dinner with guest presenter Michael Graham, engineer and principal of The Gravity Group.

Participants will also participate in the World’s Largest Coaster Enthusiast Chicken Dance and win prizes through Tweetups.
