Knock on wood—and right now it's very pertinent with what's going on in the U.S.—but we do a pretty good job at the border. We have full electronic data interchange. We installed VACIS machines right across our networks at both CN and CP. So everything that goes into the U.S. is scanned by a gamma ray machine, which really helps our profile. We have invested a lot of money in providing advanced data to CBP, but we do have issues pop up from time to time. Wood packaging material, for example, has been a bit of an issue for us over the last year or so. U.S. CBP has brought FDA within their shop so there's more scrutiny around some of the wood pests, for example. So that has impacted some of our fluidity, but all in all we do pretty well.
