Okay, watching the other vids of that guy... I call bullshit. Just another guy ****ed up in the head making fake stuff.
I mean, if that kind of shit were there, shouldn't there be people watching it?
The people were going "Cool, the fog over the river makes the rest of the city on the other side look like it's floating above the clouds." Which somehow gets turned into "OMG, A UFO CITY!!11!"
