I found this audio article while searching for an opinion on immigration from Mexico's point of view. While not one of the best articles that I have found it was interesting because it focuses on a trip that North Carolinian policy makers took to Mexico in an attempt to understand what drives them to immigrate to America and how to better understand poilicies that they put into effect.
