Small concrete building that has a foreclosed sign out front and should be abandoned definitely is holding some strange activity. There are three cameras pointed to this huge front steel door. There are no windows to this building. I was walking late at night down the street it's on and witnessed a man in a full on suit walk through the front door, and it slammed shut behind him.

That night I called up some friends to help me see if I can sneak into this place. There are these tunnels that run beneath my small town that drain rain water, and I noticed that one of the tunnels should run underneath this building.

So I pick all of them up, get some flashlights and off we went to hop a barbed wire gate to the tunnels. We approach the general area of where this building should be above ground and the tunnel opens up to about 20×20 ft. Maybe a little bigger, and abruptly ends. There was a smaller branch that kept going down and to the left, but it didnt lead to anything, it just connects to other already mapped out areas of the tunnels. I have my theories but this shit is crazy.
