A lot of Homeland Security and emissions rumblings in the future. I don't really sweat 'em until they're ready to be enacted. One of my sister companies called me yesterday. The had a Mexican, working with a green card, in town. One of his delivery points would not allow him on site. First time I heard that one. Rails and ports already require registration but I hadn't heard of a warehouse turning away drivers. Maybe that's next.
If it happens, I'll be around.
