We're a small investor in one of them just so we can follow what they're doing. The answer is that today in the U.S., about 500 miles is the number. You can say 1,000 is a better number to use. One thousand miles says it should move by rail; anything under that should move by truck.
That's probably going to get extended by at least another 500 to 1,000 miles. What that's going to do is move a lot more intermodal freight back onto the road, which will be a taxing on the infrastructure, both in Canada and the U.S. I don't think any of us are set up for that.
