We are all so blessed in the United States to have millions of acres of federal and state land that is preserved and protected. At very little or no cost, we all have the freedom to explore this great country. To make this photograph at Au Train Falls near Munising, Michigan, I got in a cave behind the waterfall and shot at a shutter speed of 1/4000 of a second to freeze the falling water. F2.8 at 1/4000, ISO 800, 18-50mm lens at 50mm
