Very nice... I really appreciate the way it's "slightly hidden," which seems so appropriate for an abandoned building.
I guess people walk away from things all the time; around here it's boats-- they suddenly "appear" in back yards and in marshlands, overgrown with vines and plants. At some point they really meant something to someone... and now all we're left with is the slight sadness of entropy.
Thanks so much for the good comment @reddragonfly
