As I've said, there really aren't that many regulations on trucking itself, so what we're responding to are shipper demands, to a large extent, for food safety. That's really one of the primary drivers for why we developed this HACCP system. We didn't want to be faced with different sets of requirements for everybody we operated for.
We wanted to have our own program so that we could say, look, we understand your need for protecting the integrity of this load, here's what we're doing internally to do it, and we'd like those systems to dovetail. That was the principle.
