Yes, it was the inspiration for the games (movie is based off the games.) My husband and I are huge Silent Hill fanatics, and when I saw this post, it was the first thing I thought of, too! I had never thought of it for a Supernatural type storyline, but it totally works....maybe you should write to the show! :P

Maybe then, they would stop featuring places in Kansas and the general Midwest that they don't know anything about...
