Des Moines is the capital of Iowa. Life here is upbeat but not too busy. Everyone that is born and raised in Iowa is very relaxed and kind. We love to say hi and help one another and we love cars. Generally, traffic is pretty good. We don't have a lot of traffic jams. However, during rush hours, you cannot move an inch on the interstate because everyone is trying to get on and off. This usually creates chaos and a huge traffic jam. In Des Moines, we have all kinds of jobs, from white to blue-collar jobs. Inside downtown, we usually have white-collar jobs. The father away from downtown, the more blue-collar jobs we have. Due to the huge population of immigrants, the city of Des Moines is also very diverse. This diversion births a hub of mulultural foods. Driving down Douglas Ave, you can see different kinds of foods from many cultures, such as Chinese, Japanese, Vietnamese, Italian, Hispanic, American, Indian, Burmese, etc. One day you can have Chinese, the next day Indian. In Iowa, Des Moines is the most diverse and busiest city. It houses many families from many different countries and still able to keep American culture and values.
