Terra incognita; beyond the bounds of civilization (some Bostonians will argue that that boundary is actually Rte. 128).
"I think a Bostonian would much rather go north or south than east to west. There is a sense that anything west of Rte. 495 needs a passport and currency control." -- John Mullin, director of the Center for Economic Development, UMass-Amherst, in the Boston Sunday Globe, 5/31/98.
