I was loading boxes of water onto a truck in Detroit yesterday when I heard the news: A convoy from the Council of Canadians was coming over the Ambassador Bridge from Windsor, bearing gifts of water. “Really, Canada?” I thought. “We’re practically in each other’s backyards. Basically, the only thing separating us from you is water.”

That’s not the kind of water you can drink, though. And also: Protest is storytelling, just like the rest of politics. I had been interviewing some people downtown about Detroit’s water crisis, and they were all going to see the water arrive, because why not? When we were done with the last water delivery, we walked down to the Spirit of Detroit sculpture, where the convoy would be arriving.

Campus Martius Park was packed with people celebrating Detroit’s birthday, which I had not even thought of the city as having. I passed a huge banner, unfurled across the modernist facade of one of the tall buildings on Michigan Avenue. Decorated with neon confetti and party hats, it looked like the kind of banner you might buy for a little kid’s birthday party, but on a colossal scale.
