Ok, ok.... I'll be nice, and do an easy one, just to see if anyone wants to play.
Show me an old industrial building, warehouse, plant, or similar that is no longer in business... desserted....
I'm talking BIG, not just a closed up storefront. I just started working in a factory that used to employ over 600 people, now we have less than 50, and will go to about half that around the end of the year.
(see Dave, I can behave...)
