From your perspective, are you aware of or in possession of any economic studies that have looked at this problem and sort of taken a view of the net opportunity that exists for us, appreciating the fact that there are multiple bottlenecks? Even if we pre-clear, if trucks get stuck on the bridge, logistically that's an issue.
Just from the pre-clearance side, what would the economic opportunity be if we had it in place in all the different areas that would lend themselves to it?
