I'll admit my own wariness about Mexico.
One of our flight crews (my usual partner and a different medic) went down to Mexico on a medical mission. Picked up a patient in a fairly small town to be brought to the US for specialty care unavailable there. On the way back to the airstrip, the ambulance stops and the driver gets out to hand a bunch of cash to someone by the roadside. A few minutes and kilometers later, he pulls over and tries to extort our medical crew. With a patient lying in the back. Didn't know our crew were military trained and unwilling to cooperate. The patient got to the US okay, but we now have orders to not go in to local hospitals on retrievals unless it is clear that the patient cannot be moved without us. This sort of incident has happened to other crews going down there, as well. Some US based flight medical crews won't even go into Mexico anymore.
For what it is worth, we do NOT have these problems in the rest of Central and South America. Not even the cartel-ridden places like Columbia.
So, for now, my wife and I are not riding down into Mexico on any vacations.
