I'm not sure being from there offers her any protection. She knows more horror stories about that hell hole than we do.
Well, I'm sort of speaking from experience here.
In the mid-1990s, I spent a couple of years in the socialist paradises of the workers and peasants.
I was on my own, including on my own dime, no one else's. Solo.
I knew nothing of the languages, and very little of the terrain. I had no idea who was an honest man, and who wasn't. Lots of times, the only way I could tell directions was by looking for a statue of Lenin (all statues of Lenin had him facing Moscow, and one could extrapolate from that).
I didn't know shit.
Others who knew the languages and the people, got around with ease.
I survived that--obviously--whole and intact, despite my disadvantages.
It still seems to me, with all her advantages, the cousin should get around Ensenada with no problems at all, avoiding all pitfalls and hazards. Unlike it'd be for you or me.
