BUT PAUSE ON KING, begin talking to folks, and the clutter, the noise of the rest of America falls away, and you are transported beyond the sometimes battered facade into a black America that, with astonishing welcome, reveals itself as not only more separate and self-contained than imagined but also more tightly interconnected, powerfully whole. Many black people have moved beyond the neighborhoods through which King runs (though there are now King streets in new black suburbs), but few live beyond the reach of the sounds, sentiments, and stories rooted on King. These are streets united by struggle and circumstance, by history and happenstance. One King street leads to the next and next and back again. For many whites, a street sign that says Martin Luther King tells them they are lost. For many blacks, a street sign that says Martin Luther King tells them they are found.
