Thought I would share this video, not sure I would have interfered. The deer looks badly injured. It interesting to me because I know exactly where that is. My parents house backs up to Hyland Lake in Bloomington, they still live there. They see yoto's all the time.
Edit: can't insert youtube videos, here is the link.
