Traditional American summer camps offer young people a chance to play many sports. These camps may be in the mountains. Or they may be in the woods, or at a lake.  Other camps teach activities like painting or music. Or they teach computer programming or foreign languages. Children at all kinds of camps meet new friends. They learn new skills and develop independence.
    Some children go to camp during the day and return home at night. These places are called day camps. Children as young as 4 years old attend day camps. Others stay at camp all day and all night. Most children who attend overnight camp are between the ages of about 6 and 16.
    Children stay at an overnight camp for between 1 and 8 weeks. Parents can pay at least 100 dollars a week for an overnight camp. Or they can pay as much as 700 dollars a week.
    Children from poor families might not have a chance to attend summer camp. There are some organizations to deal with this problem. The Fresh Air Fund is a well-known organization that gives children in New York City that chance. People around the country give money to support the Fresh Air Fund. Each summer , it serves about 10,000 poor children from the city. It sends them to stay with families in the country or to 5 camps in New York State.
