Create a detailed illustration in black and white of a group of friends fishing from a boat on a serene lake. The boat should be depicted in the middle of the lake with friends engaged in various fishing activities such as casting lines, reeling in fish, and relaxing. Include elements such as fishing rods, tackle boxes, and a cooler with drinks. The lake should be surrounded by natural scenery including trees, distant mountains, and a clear sky. Add details such as birds flying overhead, fish jumping out of the water, and perhaps a dock or another boat in the distance. The overall style should be realistic yet tranquil, capturing the peaceful and social essence of a day spent fishing on the lake. The image should be suitable for coloring, with clear outlines and defined spaces. Use only black and white for this illustration. The dimensions should be 8.5 x 11 inches.
