My wife and I flew out to Oakland to visit my sister inlaw for Christmas this year. Like any good geek who visits the Bay Area, I made a quick pilgrimage to M5 Industries, Inc...home to the Discovery channel show "Mythbusters". It was 12/26 and a Friday, so unsurprisingly the place was closed. But as the sign on the front door shows, they're not set up for tours anyway.
Originally I was thinking that the outside doesn't quite look like what I remembered from the show...only after I got home did I learn that there's a separate building, M7, a few blocks away. And without knowing its precise address, I'd never find it...the area is very industrial and very nondescript. I drove right past M5's turnoff twice before I spotted it.
Still, here's the proof! :-) Check out these pics:
