There are four canoes in the background, beautiful green grass, with three kids standing at the shore of the lake, that is crystal and crisp looking, and there is a redheaded boy wearing a red shirt, red life vest, and is in a yellow kayak, with a double ended yellow paddle.
Three children stand near a clear lake and some canoes, while a fourth child sits in a kayak holding a paddle, dressed in red.
