Geauga Lake owner Funtime, Inc. planned to add a new roller coaster – the first in ten years – to celebrate the park's centennial anniversary in 1988. Dinn Corporation was hired to install the new ride with the help of Curtis D. Summers, who modeled the design of the roller coaster after Bobs, a famous coaster from the 1920s which operated at Chicago's Riverview Park until 1967. After an investment of $2.5 million, Raging Wolf Bobs opened to the public on May 28, 1988. It was marketed with the slogan "The Legend of Terror Returns".
