| Traveling Can Help Solve the Crime Problems Americans think that travel is good for you. Some even think it can help to solve one of the country's worst problems-crime. Crime worries a lot of people. Every year, the number of crimes goes up and up. They often come from sad homes, with only one parent at all. There are problems with alcohol (酒精)and drugs (麻醉药). There are many young criminals in prison. But prison doesn't change them 60 to 70 percent will go back to crime when they come out of prison. One man, Bob Burton, thought of a new idea. In the old days, young men had to live a hard life on the road. They learnt to be strong and brave, and to help their friends in time of danger. This helped them to grow into men. So Bob started "Vision Quest". He takes young criminals on a long, long journey with horses and wagons (四轮马车)3,000 miles through 7 states. They are on the road for more than one year. The young people on "Vision Quest" all have bad problems. Most of them have already spent time in prison. This is the last chance. It's hard work on the road. The day starts before the sun comes up. The boys and girls have to feed the horses. Some of them have never loved anyone before. But they can love their horses. That love can help them to a new life. Not all young people in "Vision Quest" will leave crime behind them. 30 or 40 percent will one day be in the prison again. But that's a lot better than 60 or 70 percent. Bob is right. Travel can be good for you. Even today, Americans still say, "Go west, young men." |
