James Michener, the famous author used to hitchhike when he was a young man. Michener didn't live in a happy home. He was also unhappy at school. When he was fifteen he hiked westward from Detroit with only 35 cents in his pocket. He said, "The simple fact seems to have been that once I saw that mysterious road outside my house, the eastern part leading to a dead end, the western to worlds unknown, I was determined to explore the latter." (from Chicken Soup for the Traveler's Soul)

Most all of us have had experiences when we just wanted to get away from it all, venturing into the unknown with out a care in the world. That's easier to do when you are young and you don't have lots of obligations and responsibilities.Youthfulness tends to make us more carefree. And there is a tendency to think that nothing will happen to us.

When Jesus told his disciples to head out into the world he told them to travel light. "Take nothing with you, no bag, no money, no sandals, no extra clothing, not even a staff," he instructed them. Perhaps he wanted them to learn to trust in the providence of God. Perhaps he wanted them to experience strangers in strange lands, thereby making new relationships. Or, perhaps he wanted them to be free from the burdens of the world. I believe it was most likely a combination of all three.
