I'm not sure who I want to address this to. I'm a visitor to this committee and I'm very intrigued by this discussion.
You mentioned, Wade, that interswitching isn't used that often but the threat is very valuable. That perplexes me. I would think that the railroad companies would have some pretty good negotiators there and they would be able to deal with that. You say that it's active and it's passive. How do you explain that? You're negotiating with me, and you say, if you don't give me the deal that I want I'm going to go to the competitor. That's business, but it seems that you get away with that bluff every time.
