They just did a great episode on immigration. They hired six mexicans to build a wall just like the one the gov't is spending 60 BILLION dollars to build. The fence we are building is only 700 miles, even though the border is 2,000 miles long. However, back to the story. It takes these mexicans 8 hours to build the fence. It is 14 ft tall and has bobwire across the top. It is a two sided wall with metal on both sides. After the guys finished building it, the man told them to break up in groups of 2 people. One group was going under the wall, one group over the wall, and one group through the wall. As you can imagine all three groups were on the other side in less then 3 min.
