It's an hour drive from my part of Michigan, but I might see if I can get there to try and get some videos of them filming.
Cool, but I wonder when exactly in August they'll be filming in Detroit. The article didn't really say, just 2-3 weeks in August.
I said it in an earlier thread, but they should buy up some of that cheap Detroit real estate for explosion fodder. You sometimes hear about derelict houses selling for a couple dollars. Crack dens and the like. A lot of that stuff is due for demolition anyway... why not let Decepticons to do the work?
