Steadily blurring the distinction between illegal and legal.
Why would Mexicans want to go to Duluth ?
The blurring of that line and drunk drivers are only two of a multitude of problems. Substandard and dangerous equipment make up the bulk of the problems. Then there is the problem of crimminal mexican drivers, dealing and smuggling drugs and people etc etc etc.
My mother called me from down by Laredo yesterday. She said she called the DOT about a Mexican truck that was going down the highway with one of the axles locked up on the trailer. The driver and his several passengers just kept on going.
