Food for thought: Christmas shopping arbitrage

Counting cars at the Tucson Mall today going into and out of two of the department stores, I found that nearly 40% had Mexican license plates, mainly from Sonora with the usual handful of Sinaloans thrown in, but also a few from as far away as Mexico City (Distrito Federal).

In Tucson we're used to seeing this every weekend--at Food City, at Wal-Mart, and at department stores--but not quite at the same scale. Arizona politicians should think of that before speaking as though the AZ-Mexico relationship is one-sided.
