Mick.... Yuma? Try Nogales. Now there is an interesting city. 1/2 of the city is on either side of the border. Many tunnels go underground. Drugs and ILLEGALS come flooding through there.
mick... Yeah, illegals are a problem, but not just in Texas. I've seen the desperate poverty of Mexican border towns, and understand their intense desire to live in America. I don't know the answer to these problems, but there has to be something.
