I remember one time, this red car in front of me was pulled over, and they seemed to have found something in his trunk. After sitting there forever, they finally pulled the car to the side, and waved me on. I was shocked, because you can smuggle people in a truck easier than you can a car, yet I got waved on.
I was also shocked as I've never been out of the United States, went through El Paso, TX that day, and the border patrol was miles away in NM. Why there so far from the border?
