Somewhere, I heard someone bring up the idea, that the unidentified print on the bannister,was in such a position and angle that it looked as if someone were leaning over the railing to see if the coast was clear. Yes, I posted that on the last thread after conducting an experiment in my own home. I have stairs also, and couldn't picture what the guy was talking about. Went upstairs and started back down and then could see the only way --IMO-- it would make sense to have a handprint in that manner.
I love it, Karson. You know you're hooked (as am I) if you are conducting home experiments. LOL!!!!! Good idea actually.
