I have experienced all three that you mentioned. There are people who want us to dumb down to the lowest. They usually get told they can't. There is pressure to harmonize the north and south, or all three, and there is pressure on the Europeans. Generally so far the system has been able to argue against it, but I see a continuously ongoing drive. The drive is trade, so we have to be aware of that.
We had a fire truck standard that required a fire truck to have a steel ladder. The City of Montreal asked why that was, and we said it was because 20 years ago somebody made a steel ladder. In some cases, we've had some things that were a little bit of a trade barrier. I think when we go through the upcoming agreements we're going to hear more of this, and we have to be prepared to have a considered and well thought-out answer.
