My wife is from there and She is very tall. She says no one in her family feels safe there, and they have massive land in a rancho. Research what you are about to do, no one in her family in the US, will cross that border in this state of things. Many in her family have just disappeared without a trace over the last few years, cousins, aunts, uncles gone, just gone.
Really, you would have been safer in the jungle against the VC, and the NVA in Vietnam than Mexico today.
Just want to add best of luck, have stacks of twenties to bribe the cops, as they will not be your friend.
There are plenty of Latinas here, why take the risk, and he is right no water or ice cubes. I miss going to Mexico but, the drug cartels are everywhere.
You also must, must speak the Spanish in Mexico, or you will be lost.
Again, best of luck.
