Back to the question I had about the cost, which I estimated in the billions of dollars, whether it's $10 billion or $12 billion, I wondered how those costs get absorbed and how they get passed on. If I understood you correctly, you're basically saying it's a market thing and it is going to be built into whether it's economical for you to transport that way.
Might the cost of replacing these DOT-111 cars or increasing the capacity of the transload facilities mean that the cost would be such that means other than rail would be considered?
