Raging Wolf Bobs was a wooden roller coaster located at Geauga Lake amusement park in Ohio. Designed by Curtis D. Summers to resemble Bobs, a popular roller coaster at the defunct Riverview Park in Chicago, Raging Wolf Bobs was constructed by the Dinn Corporation and opened to the public in 1988. It operated until June 16, 2007, following an accident involving the derailing of a train that unexpectedly rolled backward on one of the track's hills. Later that season, park owners Cedar Fair announced the permanent closure of Geauga Lake, sealing the fate of Raging Wolf Bobs.
