I think the TSB is great. They showed up on site. They came out there to take a look at it and they're more than willing to always tell us, “Listen, we see something here that you should take a look at.” I think they are a nice, clear conscience to look at it. They're professional. They know what they're doing.
Transport Canada shows up and looks at it to see if there's anything and they give us feedback. If we don't understand something, we're willing to hire anybody, whether it's the transportation centre in Pueblo, Colorado, which every railroad in North America works with; scientists who look at the infrastructure and at what we can do on the railcars; or we do it ourselves, by going to universities that we partner with. It's very important that we get to the bottom of it.
