I would say it's more on the modernizing side. If there were new vessels, and certainly if there was a depth change, then of course all ports would probably be affected on the Great Lakes in regard to what they could handle. You would have to find out what that modernization of the seaway was before you could answer the other question.
In regard to what exists today, you're looking for things to maintain what you have at a high level. Quite frankly, there's a possibility that maybe there are new ways and new technologies out there that could make it a more efficient operation as well.
