Puzzles #679 & #680 - Twin Snakes (Slitherlink)

I also made two Slitherlink puzzles as potential submissions for Logic Showcase 56, but elected not to submit either. I don't remember which of these was better than the other, but I do remember that if I had other good slitherlink ideas or other similar ideas for other genres, I was going to throw it in. Ah well, it is what it is.
