When Bill Hillmann joined this year's running of the bulls in Pamplona, Spain, he knew exactly what he was signing up for. After all, he co-wrote the book on it.
Hillmann was a contributor to Fiesta: How to Survive the Bulls of Pamplona. But his expertise didn't protect him from harm this year: A lone bull, or suelto, gored him through the right leg.
From his hospital bed, Hillmann tells NPR's Kelly McEvers that he feels fine. "They've got me on some really good painkillers, so I'm just kind of floating here," he says.
