Before the days of postal zip codes America had a system of zones to indicate to the Postal Service in what part of the country our communications and parcels were to be delivered. It seems that "zones' are coming back into vogue via social and cultural engineering and liberal thinking.
There may not be much legitimate thinking connected to our new zoning maps, but as E Pluribus Unum gives way to the new millennial and "alpha" generation kind of hyper-personal ideologies. The day may be near for each to, metaphorically speaking - have their own zip codes.
