We actually live in Mexico (full-time missionaries down there since 1987). We went up to in El Paso, Texas for a 2 day shopping/supply run when it happened. We're very grateful it happened here and not out on the highway somewhere. We have a safe, comfortable place to be while waiting for it to come back. We're thinking of jumping on the Amtrak to Arizona to visit some family there while waiting. Once there we can borrow a car. Friends let us borrow their car the other night to get some groceries with (I was getting tired of Dominoes pizza for every meal). We're good.
You have my utmost respect for serving in what has become a danger zone. In 1970s El Paso, we'd quick-trip over the free bridge to Juárez for 50 gal of diesel at 7¢/gal, a couple six-packs of Negra Modelo (for $1.25/ea), and sandwiches with a side of jícama from a street vendor at the nearby park.
When the cartel wars came, several people were slaughtered at that park, a formerly peaceful place where old men gathered daily to swap stories. By that time, our diesels were gone (and so was I). Most of that violence has subsided now, but I'll likely never re-enter Mexico, even for cheap diesel. Stay safe!
