The debate over building a U.S.-Mexico border fence often ignores one key issue: the fence that's already there. It's a disjointed mishmash of various barriers, structures ranging from wooden fences to high, steel mesh walls. 

Peter Skerry argues in the most recent issue of FP that these disjointed barriers reveal America's ambivalent and conflicted attitudes about immigration. I wonder what he would make of this new use for a section of the fence south of San Diego: the first-ever game of international border volleyball.
