Almost everyone knows what Bigfoot looks like. We've seen those six seconds of grainy 1960s home movie footage where this furry, hulking figure looks over his shoulder at the camera, then disappears into the California wilderness.

But not many people know what Bigfoot sounds like. Rich LaMonica says he does.

For seven years, the Akron truck driver has been carrying around what he believes is the only recording ever made of Bigfoot saying something. Exactly what he's saying is uncertain. Even LaMonica, who wants to believe that this tape could be the missing link, has questions...His odyssey began in 1988, when he was driving his truck route from Coshocton. Ahead in the distance, he saw a large, dark creature cross the road and disappear into the woods.
