Last weekend I took Jan to Milwaukee for a trade show. While she was at the show I met up with Tim and we spent the day exploring Milwaukee and the surrounding area. Just south of the city, in South Milwaukee, there is a park called Grant Park. The Oak Creek enters Lake Michigan in the park, and the road into the park, Oak Creek Parkway, follows the creek. We spend a lot of time in the woodland around the creek, and I posted some pictures from there to my flickr photostream last week. At one point the valley opens out and there is an old mill pond. This photo and the accompanying sound are of the water flowing over the top of the dam at the head of the pond.
