NAFTA does what?

Yesterday I had to ship a laptop computer to Canada.  It took me two hours to set it up and add all of the programs.  It took me four hours to complete all of the paperwork and when I got to FedEx, I still had to correct some of it.  Really, was all of this needed?  The real entertaining part is that if I was to get on a plane with the same laptop to fly in, have lunch with the recipient and then fly home without the laptop, no questions or paperwork would be required.  Now I remember why I normally have the shipping department handle international shipments...
