This must be a good 45 minutes from the border, and each vehicle is looked in for illegals, and they have drug dogs. I assume every highway has a check-point. There are many INS - SUV's, and I've seen them all over down there. Many Illegals have died trying to walk through the King-Ranch area.
What?? The US Border patrol and the INS are Federal agencies pal. Gezzz, wake up, or get out of the GD Texas sun.
