Yeah, I took another picture right after it of the same stairs and the black mass was not there. When reviewing it, I kind of thought at first that it might be spray pain until I went to the next shot. It definitely was not visible when I took the shot. It was also on the fourth floor, which is supposed to be the most haunted and also where the TAPS crew caught the shadow person on the FLIR.
Looks cool. Do you have any other photos of this same spot without the shadow? Only asking cause I have seen how much spray paint is in that place and the photo kinda appears that the black mass is on the steps.
I am thinking of starting a free banner exchange for anyone with a paranormal website. If you think this is a good idea then let me know. If there is enough interest I'd start it up.
