I was walking through our backyard in the late afternoon, when I looked down as I was about to step. This snake was staring up at me, mouth open, where I was going to put my foot. I ran inside and grabbed my camera and took the pictures I wanted; after a quick search, I confirmed it was a Water Moccasin, a venoumous water snake. My brother, my father and I then proceeded to go out and attempt to kill the snake, but we could not find it.
Note the triangle shaped head
