Thank you for the question. I absolutely agree that physical infrastructure is certainly key and we wouldn't want to overlook that. It's something that UPS certainly pays very close attention to in the context of international trade.
On the perhaps somewhat less tangible side of infrastructure, one thing we're looking at in the context of NAFTA and particularly the movement of goods from Canada to the U.S., is enabling dedicated fast lanes to operate a little more efficiently. At present, there are restrictions on who is able to use those fast lanes and what kind of mix of load you can have in your truck as it crosses that border in order to benefit from the fast lane. We'd like to see some of those rules changed to enable a broader range of those who are transporting goods to use those dedicated fast lanes to move across borders.
