In 2005 my friend Maggie took me to see the Delray neighborhood of Detroit. Maggie, a native Detroiter, told me that it had once been a vibrant neighborhood, but had fallen into decay.
A local artist, Carl Kamulski, decided to help by decorating the neighborhood with angels. He cut 114 of them from plywood and people pitched in to paint them. The angels were then hung on businesses and decrepit buildings.
Recent articles about Delray refer to the neighborhood as abandoned and the closest thing to a ghost town within Detroit.
I don’t know if the angels remain.
