Depends on the day. The cartels do what they want, waging their battles all along and through various border towns. and you have to keep your head on your shoulders. Being a gringo brings no special protection or status, either from cartels or from dirty government officials. Sasabe, AZ used to be a quiet little border town west of Nogales, for example, but two rival cartels have moved in to battle one another, and collateral damage isn’t something they care about. Naco, Agua Prieta just to the east…all have the same problems. From Falcon Lake to the LeBarons, bad events happen fairly often, they just don’t all get the attention that some do. If you go, go in, get what you need done, and leave.
