What if you discovered that a giant tunnel ran 20 feet underneath the entirety of your town? That’s the case if you are a resident of Hinsdale, Illinois. A two-mile tunnel runs through the entire town. There is a main tunnel, with many smaller tunnels that feed the main one. We really don’t recommend trying to walk through this tunnel. You can get a great idea of what it looks like from this video.
