The Bobs at Riverview Park in Chicago, Illinois is considered by some roller coaster enthusiasts to have been the ultimate wooden roller coaster. It was built in 1924 and was demolished with the rest of the park in 1967. The Bobs was built by Frank Prior and Fred Church at a cost of $80,000. The Bobs had a maximum height of 87 feet (27 m), a drop of 85 feet (26 m), and reached speeds of 50 miles per hour (80 km/h).
A modernized version was located at the now defunct Geauga Lake in Aurora, Ohio, and was called Raging Wolf Bobs. It was not as intense as the original Bobs. The Bobs was immortalized in American humorist Jean Shepherd's August 26, 1967 broadcast.
