After the 1921 World Series, the Bambino and teammate Bob Meusel began a barnstorming tour in the Northeast. The new baseball commissioner, Kenesaw Mountain Landis, had warned them against doing it, citing a ridiculous and seldom-enforced rule. Greed overruled logic, and they did it anyway. Landis responded by suspending both players for the first six weeks of the 1922 season.

A year later, Landis had waived the rule. And after losing the World Series in 1922, Babe Ruth and Bob Meusel left the harsh glare of New York for an eighteen-game Great Plains barnstorming tour. Stops included Omaha, Kansas City, and Denver. But also Sleepy Eye, Pratt, and Tarkio.

They played in sleet, rain, and snow, traveled overnight on "jerkwater" railroads, and tolerated endless civic celebrations. They hit monstrous home runs, played against formidable Negro Leaguers, and faced some great small-town pitchers. They also visited orphanages, raised money for the American Legion, and created lifelong memories for hardscrabble farmers who would have never otherwise had a chance to see a major league baseball player.
