I think as a community of airports, we're always looking at what's out there and how to improve things. Our organization is part of an international network. We work very closely with colleagues in the United States and around the world, so we're there at the forefront of technologies and innovations that are being developed elsewhere. We're always looking at what we can do to do things better.
The way we're structured, airports have been able to invest $22 billion in their own infrastructure through the use of user fees since airports were transferred in the early 1990s. Airports are able to take advantage of technologies and innovations. Sometimes our partners in government find it a little more difficult because of a strain on resources, as we've been discussing today, but I think it's certainly a priority for everybody in the industry to make sure that we have access to the latest tools and the most effective tools for everybody to do their jobs.
