Well, again, it depends on which area you're talking about. I've heard of cars sitting on the sides, not efficiently being used. That is a problem. That's a service issue, in my view. There should be no cars sitting around, because there's lots of product to move. I would say that is an inefficient use of the scarce resources that we have to move this product. If there are things like that going on, then that could be looked at as to why.
