Prompt
"Generate an image of a serene river flowing through a picturesque town, surrounded by lush greenery and featuring a historic bridge in the background. The river, a 16.3-mile-long waterway in Massachusetts, United States, should be depicted in a realistic style, with a gentle current and possibly a few kayakers or canoeists in the distance. Include subtle hints of the river's rich history, such as a few sailboats or a distant monument, but keep the overall atmosphere peaceful and natural. The Old North Bridge should be visible in the background. Style: realistic landscape painting."
