There are a couple of pieces to that. On the one hand, the more we do to make it easier for people to get a document that will let them cross the border conveniently, the better. On the other hand, I think there is an issue of proliferation of cards. At the consumer level, I'm worried that the enhanced driver's licences aren't going to be ready in sufficient quantity to prevent back-ups this summer, and I'm not sure how long the implementation period may be.
Moreover, with the enhanced driver's licence at the consumer level, as with commercial accreditation like FAST or NEXUS, what's really important is that there have to be clear benefits if you go through the effort to get the enhanced documents. You have to make sure that they get you through the border faster and that people see it happening, feel it happening. Ultimately, that's what's going to convince people to go through the extra effort to get those documents. That's what's got to happen if we're going to get smooth traffic on any of our border points.
