Anne Harrington: So you walk into the building, and first you have to walk up, right? many floors, so that you can get to the top of the fermenters. And then you look down, and it's like looking into the Grand Canyon. Just absolutely gargantuan. And a whole row of them, you know. One wasn't enough, you had to have a whole row. And then there was a separate building where they did the milling. There were bunkers where they filled munitions.
