ApesForEvolution: I live right here in Minnesota, which , as you know, borders Canada, but I know, also that there are freight trains that come right up from California, go into Canada and back out. These trains go in and out of small towns, and can easily board hoppers up to no good, when the Mexicans forget about Our Lady, and are down and out, with food or money on their minds, watch out! But they don't carry suicide belts, but their little Islamic friend might.
The MN State Legislature shot down Governor Pawlenty's attempts to even put non-resident alien status on Driver's Licenses IIRC...
