From his earliest days exploring the woods near Clifton, Bob Genheimer knew he was interested in digging up history. When he learned what archaeology was, he finally had a name for his passion. And that's how he ended up in a toilet. Many toilets in fact - 19th century privy shafts, it turns out, are treasure troves of knowledge. One of Bob's favorite stories involves a policeman in a privy. We'll talk to him about that, his first experience at Union Terminal, and the dig into the course of his career, which includes 33 years here at CMC.
