As I said, we were moving record volumes in the fall. We felt we had our car fleet sized to what the ports could handle. When we saw in the fall that, in fact, it appeared the ports could handle a bit more than we thought they could, that's why we decided to add the cars.
What was said in terms of adding cars to a congested system, that's the reality we deal with. If the ports are congested, adding more cars is the worst thing you can do.
