Borders

The Edge: "THE EDGE persists, hard at work, on the margins of everyday life. It works as jumping-off place, hang-glider launch, view property, or point of no return. For insular people, it delineates THE EDGE of the universe. It is where one distinguishes here from ther—the latter located out in the Great Beyond, another country, a yawning abyss—or simply not-here." [Ref. 3]

Twilight Zone: "Like other place-names which begin in the crepuscular dusk between physical realms, TWILIGHT ZONE has migrated—along with its obscurities—into sociology and common usages, each of which specializes in neither-this-nor-thatness. It can denote space occupied by the social demimonde, or a disputed workplace between two labor unions, or a seldom-policed and dimly lit street, or a neighborhood frequented—but how can you be sure?—by refugees from myriad classes or ethnic groups."
