Downtown Houston has a massive 7 mile underground tunnel system that most people don’t know exists. One of the main entrances on McKinney and Main is difficult to find. Signs don’t mention it. People standing nearby can’t provide much information. This video shows my attempt to locate it and see if you can actually get into the area after 5 pm.
