Yeah there is the wall / fence. Going into Mexico pretty much isn't monitored. You can just walk right through the fence. When you come back to the United States you have to go through border patrol and have your passport and all that. I guess we are driving across though and going a little further away from the fence. My friend knows what's going on and the dentist we are going to was recommended to her. So we will see. If I determine this dentist to be a scammer like the guy in Tucson I will get the hell out of there. It is always hard to know though. lol
