The last snake in your video is a King snake but still to this day I don't always remember the colors. I recall stepping on a coral snake not quite 2 feet long while standing facing my tool bend on my truck some years ago. I could feel this wiggling and jumped back and to my surprise it was a coral and it didn't even come up at me to start the chewing on my leg or anything. We have super large Diamond backs but they are beautiful creatures. 5+ inch diameter snakes. The only thing I am scared of is a Cottonmouth snake as they are a crazy a$$ reptile that will chase you down.
