Ran across this urbex video, watched it and its sequel:
It's filmed across a few buildings in Milledgeville, GA near the central state hospital and the more you look the video and the area where it was filmed, the more questions are raised. Pripyat seems absolutely mundane next to this place, because Pripyat makes sense. An abandoned town abandoned for understandable reasons. But this area in the south of Milledgeville is like a weird 50/50 medley of ordinary functioning town and giant abandoned buildings - mostly hospitals, mental hospitals and prisons.
Strangest of all, at one point around the 23min mark they enter what is clearly an actively used building through the utility tunnels that connect many of the buildings in the area. It's what looks like it could be the basement hallway of a hospital. In this hallway, there's a door with a sign on it: "WARNING: COMPUTER IN OPERATION. WALKIE TALKIE MUST BE TURNED OFF WHEN ENTERING ROOM."
The more you think about this sign the less it makes sense. No modern commercially produced computer is vulnerable to interference from a walkie talkie. Could it be some prototype or maybe a quantum computer? What kind of facility is this where people commonly use walkie-talkies? It's also curious that doesn't say don't use, it says turn off. Is merely being on a problem? Is it hosting some AI that can listen in on what's happening in the room? Why is the bottom of the door taped up? Why is there a hallway branching off to the other side with a totally different style that looks more like a house? I haven't been so confused by a place since I drove through a former military base that was used as a school and then as a temporary prison.
