There is no way in hell you can make a wrong turn into Mexico. I know i live close to the border, i was 15 miles away from Mexico today. Once you start going south about 100 miles from the border you pass your first checkpoint. This checkpoint only checks cars going North, However it gives you an idea that you are nearing the border. When you finally reach the border you pass American immigration first then Mexican. But before you get that far, you usually have traveled over a bridge or through a huge checkpoint. No way he made a wrong turn, no way. I feel for the guy and think he needs to go home but lets hear the truth.
