Hidden Message

When I first pulled this up I didn't like it and almost deleted it as it didn't come close to portraying what it was like in real life. Then I saw the scribbled message on the side of the wall that I couldn't see when I took this picture as it was much too dark.

Picture is a 6 minute exposure (it was DARK - I was using the LCD screen on the back of the camera as a flashlight to walk around). The backlighting is from a couple of the refineries on Sarnia's waterway.
