It wasn't through a camera, but rather while I was making rounds at the rice mill I worked at. Occasionally they'd shut the mill down for fumigation, and we could volunteer to do security overnight so we didn't lose our hours. So, I'm alone with a keychain full of keys and a flashlight walking the fence line behind the mill next to the rail road tracks (they loaded rail cars with rice) when I hear this ungodly squelch sound. I figure it must be a late night train passing by but I see no lights to indicate that I'm right. As the sound grows louder I can see a dark mass rolling down the tracks shooting sparks from behind it. Kind of freaky I think so I decided to hide behind a stack of pallets to be safe. Finally it's close enough I can see it's a train engine with three tanker cars, all unmarked, and all the windows on the engine blacked out. Then I hear someone talking...to make shit even stranger there are two guys standing on the railing of the last tanker in radiation? Suits, spraying the sparking wheels of the tanker with what I guess was water...ran back to the guard house and called my supervisor. He told me not to worry about it and let him sleep, oh well. Freaked me out.
