Mr. Christopherson and I just had a conversation on the side about NEXUS cards. When there's a big lineup, I love my NEXUS card, but I can't quantify that for you; I can't tell that to you. Yet, if there's a small lineup, you wouldn't necessarily see the benefit. I look at that in the same way as I do at border crossings. When you have a huge lineup, and you have a NEXUS card, and you get to go along the side and pass three hours worth of wait, I can see the benefit, but how do I quantify that? How do I put that into a number that extracts value? How do I say to you guys that having that extra hour and a half to travel and not waiting at the border saved me $100,000? Again, I can't do that, and there's no way to find that out. I can definitely see your issues there in how to put that model in place.
You're six years into communications or technologies. How do you know that the technology you have now is still current and still the best of the best? It's already starting to be six years old with lots of changes. How do you keep that up to date, and how do you keep improving that?
