［1］When children go to camp, they are on their own, sometimes for the very first time in their lives. They have to decide what to wear, what to eat and which activities to participate in. As a result they develop confidence and independence.

［2］As self-respect develops from learning to be on their own, children continue to try new activities. Also it is possible that they will engage in what they are unfamiliar with. In school, children do not experience success in the same way. Camp can be a school without failure because just having fun makes them a success.

［3］One of the greatest benefits of a camp experience is that children develop social skills. In a camp setting, a good counselor will make sure that every camper is included in the activity and that each child interacts with the others in a positive way. They learn to give and take, and they learn how to work and cooperate. Something as simple as clean-up, is not only there to get the cabin clean, but to promote a team atmosphere of working together which in turn results in friendship.

［4］The obvious benefit of camp is that campers make long lasting friendships. These friendships can often be unique and special because campers are living with each other and see the true personalities. Chi1dren learn to see others from a different viewpoint. Children tend to be accepted for who they are and do not have to be concerned about what they wear, what they are good at and how they look. This is because in a camp setting, respect and caring finally win out over materialistic objectives.

［5］In a word, camp does give children fun, friends and fulfillment.
