gary, what a frightening picture (to me)....there seems to be life only behind one window...guess all the other people laying on the floor afraid of the photographer??? or maybe they all making love at the same time....or the place had a mass evacuation.....pix has a touch of (former) east-berlin also..or cagefree chicken advertising....oops..missed one window...third row from the bottom...
its a crack open....maybe the cleaning person needed air...endless stories could be spun...
thanks ....:))))
