In 1912 boxing was as popular a spectator sport in the United States as baseball, if not more so. It was also rife with corruption and surrounded by gambling, drinking, and prostitution, so much so that many cities and states passed laws to control it. But not in New Mexico. It was the perfect venue for one of the biggest, loudest, most rambunctious heavyweight championship bouts ever seen. In Toby Smith tells the story of how the African American boxer Jack Johnson—the bombastic and larger-than-life reigning world heavyweight champion—met Jim Flynn on the Fourth of July in Las Vegas, New Mexico. The civic boosters, bursting with pride in their town, raised a hundred thousand dollars for the fight, pushing events like the sinking of the to the back pages of every newspaper. In the end, once the dust finally settled on the whole unseemly spectacle, Las Vegas would spend the next generation making good on its losses.
