As spencer said, I've only heard the city names in reference to the orientation of the Box. And as stated previously, the references change based on where you are. In San Francisco, we've worked in San Francisco due to it's hills. So LA is flat, New York is on Tall ways, and SF is on it's side. I've usually heard First position, second position, and 3rd position more frequently, first being flat, 2nd on it's side, 3rd tall ways. More often than not though the need is obvious and you'll just call for the apple by size, eg. full or quarter, or just say 1/8th apple flat, or full apple on it's side.
