Okay. This strikes me that it's a little bit like buying a car where you're quoted a base price of $20,000 and then the question is, do you want an engine, doors, a window? The list you provided seems like that to me.
The other question I was going to ask was about the issue of the track.
Mr. Sobkowich, what is a duopoly versus a dual monopoly? You said there's a difference, and I'd like to know what that is.
