We obviously have an extremely diverse port. There aren't many ports in the world that handle as wide a variety of commodities and products as we do.
There could be instances in which that could make a difference, but generally speaking cargo flows to a port for a reason, whether it's a particular railroad in their network, or whether for some reason it has proximity issues, if something is moving out by truck.
Generally speaking, in the majority of cases there is a reason traffic flows to the port it does, so there could be places on the margins where traffic could move, because of capacity issues. Overall, I'm not sure this would be a terribly successful strategy.
