ATLANTA (AP) — Today, Auburn Avenue is a shell of its former self. The bustling mix of banks, night clubs, churches, meat markets and funeral homes is long gone, replaced with crumbling facades and cracked sidewalks.Hundreds of thousands of people still flock to Auburn Avenue to see King's birth home, the church where he preached, and the crypt where he and his wife, Coretta, are buried. But tourists have little reason to linger.While King's legacy has been preserved, Auburn Avenue's business community has never recovered from the exodus of the black community that supported it. This week, the area was placed on the National Register of Historic Places' 11 Most Endangered list for the second time since 1992. The hope is that listing will spur preservation-oriented development.
