From my current post at La Plaza, on the Easter Sunday earthquake centered south of Mexicali:
It is the strangest thing about life in the far northwest of Mexico and far southwest of the United States. The international border is there, policed and guarded, its crossing coveted by millions -- for Mexicans, to work, for Americans, to "get away from it all." The boundary divides the First World from the developing world, the wealthy neighbor from the poor one. But in so many ways, the line is invisible, not there at all.
