The Things We Lose Without Knowing--the Milky Way

From Kottke -- most American kids will never see the Milky Way (from their home, I suppose).  Some, maybe even most, change is good, but some isn't.  (Though I suppose the people in this world who can see the Milky Way are often in what we used to call the Third World.  There's always tradeoffs--did Robert Heinlein write that?)
