Riding the rails was dangerous. The bulls were hired to keep hoboes off
trains, so you couldn't just go to a railroad yard and climb on. Most
hoboes would hide along the tracks outside the yard. They'd run along
the train as it gained speed, grab hold and jump into open boxcars.
Sometimes, they missed. Many lost their legs or their lives. As the
train was reaching its destination, the hoboes had to jump off before a
new set of bulls tried to arrest them or beat them up.
