The purpose of those pilots was more to test the concept of cargo pre-clearance. It was a pre-inspection pilot where we were doing pre-inspection in Canada with still the potential need to go to secondary inspection in the U.S.
Those sites were chosen because they have a significant amount of traffic and for other factors like that, but it isn't necessarily where we would end up having pre-clearance. It was really to test the concept and how it operated, so each element about those pilots was testing different aspects of that.
