There has not actually been a tremendous change in the number of incidents. In 2004, we recorded 7,500. In 2006, we recorded 8,500, and in 2008-09, we recorded 9,000. So there's been a little bit of growth, but in some years it also fell somewhat.
What we have found with the technology and the 406 beacon in particular is that a number of our operations have been a lot shorter, and therefore the number of people whose lives we have saved has increased, because we've been able to respond with precision and current data by using the technology of the 406 beacon.
So I think overall the technology has driven a more efficient and capable system, but the incidents continue to happen at about the same rate.
