It is. I think the number one development is much better internal inspection tools. Internal inspection is routine for these large diameter pipelines, much as medical technologies have advanced considerably in terms of imaging and an ability to see inside your heart, let's say. You can determine without having to see with your own eyes that there is or is not a problem or what you need to monitor.
Also, that data feeds into much more advanced integrity management systems, and that has allowed us to have a very elaborate system in place. There will be mistakes from time to time, but the trend line is very positive and will continue.
