Before we bought a house, we lived in an RV fulltime and spent 5 winters near the Mexico/US border. We stayed at 3 locations in the Rio Grande Valley of Texas and traveled the Texas/Mexico border all the way. We also spent one winter in Casa Grande, AZ. Most of the wall is already in place, it was put there by Bush. It was working until Obama pulled the border patrol away from the border and moved them North so the fence was left unprotected. The Mexicans have destroyed it in many places. We didn't need to spend more money on a fence, all we needed to do was keep the border security in place that was already there. I know some of you are going to say Obama has done more to stop illegals than Bush, but that's more BS. I have spent a lot more time there than Obama. As far as I know, he has still never been to Arizona except when he landed in Phoenix and Jan Brewer shook her finger at him. No place on the US/Mexico border is safe.
