Edit again: Took a slower drive through in the light yesterday. The building in this thread is definitely down, the site looks cool though. They saved one of the green tower things and it's at the fence in front of the foundation. This was before Min security heading towards Pontiac.
Now after Min, there's another building that's boarded and newly fenced off. No trucks there but the new addition of the fence leads me to believe this one is coming down in the very immediate future. Strangely it's attached to a working portion of the building (lights on, steam coming from chimney) but this half is in poor shape. Think we found our A and D.
Also if you continue to another area of the complex there's another boarded up building similar in appearance to the one that just came down as well as an abandoned house.
