Our understanding, or at least my understanding, is of work that actually goes on in a different area. I'm not an engineer and I don't have the technical capability to do the assessments myself, but what I'm told by our engineers is that accidents happen less often with pipelines than with other modes of transportation, so we think pipelines are the safest way, the least accident-prone way of transporting large volumes of oil and natural gas to markets.
That said, we're not really in a race with anyone. We're not trying simply to be better than rail. What we're trying to do is to provide the safest pipeline infrastructure for Canada, and so we're continually working to make the pipeline system safer, and safer yet, and safer yet again, and then to be prepared for to respond to an accident quickly, if one does occur, and to be able to clean up the accident and reduce its effects and to do those things in the most appropriate way.
