We went to Oil Creek State Park, PA (the first USA oil wells, in the 1850's) just to wander and maybe take photos. There weren't any water birds or eagles to be found, so I wandered around the grounds of the museum area. The exibits were closed, but I tried to look into windows of old building to see what might be inside.
They were very dark, but I could see outlines of machinery in one, and maybe a tractor in the other. On a whim, I put my camera to the windows, used 8000-10000 ISO, manual focus, and clicked away.
These are the best of several attempts.
