There's a lot to be said about traveling in a boxcar, especially an empty one. You can get up and walk around or even trot. You can sing, holler and shout. You disturb no one, if you're alone. Through the wide open door you can watch the countryside go by; you can smell the country air mingled with the odor of sulfur, as the fireman piles more soft coal onto the fire. When it rains, there's a roof over your head. When the wind howls, you can always close the door a wee bit more to keep out the gusts and the cold.
For a novice, danger lurks in and around freight trains. They exact a heavy toll in injuries and deaths. Fortunate indeed is the man who can ride with a few old timers.
