7、risscrossing a careworn street on Detroits west side,looking at the house where my mother lived in the 1930s.I walk up driveways,down side-walks,peer around bushes.A neighbor,understandably curious,bounds over.“Im the king of Glendale,”Keith Harris says.Harris loves Glendale Streetso much so that he

13、babies.”Maybe they shouldnt have.Though much is gone and more has changed,there are seeds of hope across the city,as writer Susan Ager and photographer Wayne Lawrence discovered while docu-menting the diversity of the new Detroit for this issue.Harris has planted some of those seeds.“We invest in th
