Swimming Deer
I was fishing on Echo Lake with my buddy in Manitoba's Whiteshell Provincial Park, when we saw something in the water. As we got closer, we realized it was a deer. She seemed to know where she was going, and was surprisingly fast. We kept our distance so that she wouldn't be too stressed, but she still kept an eye on us and disappeared quickly once she got ashore.
