This is an old coal conveyor in an abandoned power plant, which has been adorned with some rather ominous graffiti. At least it probably seemed ominous to the person who put it there. :)
And yes, all that shredded white stuff falling down from the pipes is indeed friable asbestos. Needless to say I didn't hand around here long.
It was too interesting a shot to pass up though...such wonderful textures!
