It's famously known as Elvis Presley's favorite roller coaster, which is why it fittingly took a moment of silence on the 35th anniversary of his death.
According to WLUK-TV, the Zippin Pippin, which is now at Bay Beach in Green Bay was shut down for a few hours Thursday after it become stuck.
The Parks, Recreation and Forestry Department tells WLUK riders were aboard the coaster at the time.
Days before his death, Elvis rented out Libertyland, the roller coaster's original home in Memphis, Tenn., for an overnight party.
Bay Beach commemorated the anniversary of that party last Wednesday by keeping the ride open an extra two hours at night.
