I do not. In fact, one of the real difficulties we had was getting origin and destination information on what is shipped through there. As a result, our work was a lot more difficult. Apparently a lot of this is considered proprietary information. We were able, from the Corps of Engineers, to get what's called “past the point”—what was coming in one direction or another and what was in the load—but we couldn't find out where it came from and where it was going, and that made things difficult.
I really don't know. My guess is there's probably not a huge amount that would go through that area from Canada, but I really don't know.
