That they filmed a scene of the Dark Knight Rises in it. 

It was around spring of last year that this thing appeared at the end of the parking garage:

I just remember thinking, ‘wtf is that, why is it there, eew, make it go away’ 

About a month after it disappeared, I found out that it was used for a scene in the upcoming Batman movie.  Yah, I know right. Christian Bale was at my school >_> 

So long story short, here is my schools lovely parking garage that Mr. Bale stepped foot in while I had no idea what was even going on. Yes, with a little CGI magic, that is indeed the interior of my schools parking garage.
