For a few months shy of a year, I called Detroit home in 1995. I loved the city and the people I met there. I loved its architecture and its sadness, its empty streets and surreal highways. It was an endless phantasmagoria, and I barely scratched the surface of its richness. Detroit is the jumping off point for a PBS documentary, funded by the Rockefeller Foundation, that looks into the public transit mess that afflicts so much of the United States. I reviewed the film in today’s Post.
