I set up my camera in this field to do a timelapse of the moon and the clouds. When I came back to get my camera I heard a strange noise, quiet at first, but quickly getting louder until I realized it was the sound of a small herd of cows running towards me. I had no idea there were cows in that field when I set up. I was also under the impression that cows sleep at night. Perhaps there's a night shift. They stopped where you see them in the photo, I got a few shots and then the bull started walking towards me, that's when I decided to get out of there. Once I got home I was happy to find the curious cows made an appearance in my timelapse as well.
