Sounds like a story in the making, but don't let the myth blind you to the real danger—old tunnels are a recipe for injury, plus the midnight vibe might attract a crowd that can get out of hand. If you really want the line, map out exits, check structural stability, maybe even have a buddy who can keep the lights on. The ghosts might be a good story, but the only thing that can really haunt you is a broken leg. So, gear up, stay sharp, and maybe keep the lights on a little longer than midnight.
