Creelman traveled extensively to find stories and was unafraid to take on great personal risk in their pursuit. He joined adventurer and showman Paul Boyton on his treks across the Yellowstone River and Mississippi River, dodged bullets reporting on the feud between the Hatfields and McCoys and interviewed Sitting Bull. He also interviewed Mexican President Porfirio Diaz, wherein Diaz stated he would not run for reelection in 1910 to allow new leadership for Mexico, a promise he did not keep and that in part led to the Mexican Revolution.
