Certainly, we do have one of the largest undefended or open land borders in the world, but we also have excellent relationships with the U.S. authorities and our partners.
It does present challenges. We clearly have large commercial transportation networks for legitimate goods that transit throughout North America. Those also present opportunities for organized crime elements to manipulate those transportation routes to import illicit goods.
However, we have had great success and we continue to have it. The border presents challenges, as you're aware, but we've increased our technological aspects, our intelligence aspects and our joint enforcement aspects as well in combatting those crimes.
