A 1974 newspaper photo from the Citizen-Standard (Valley View, Schuylkill County, Pennsylvania) of the paddle wheels of The Roaring Bull, one of the Millersburg Ferry boats in service on the Susquehanna River, Millersburg, Dauphin County, Pennsylvania.
The caption states:
These paddle wheels propel The Roaring Bull across the river.
