On the question on the integrity of the borders, there are mechanisms to make sure that the trusted trader programs are properly supported, such as the free and secure trade program, as well as the U.S. customs trade partnership against terrorism, and the Canadian partners in protection program. The more those kinds of programs are supported and expanded, the better that scenario will be addressed. We're dealing with the ability for supply chain security all the way back to the factory, if it's a manufactured good, through to the destination, rather than just the transaction at the border. By then it's too late.
