It's a reference to the perception of Detroit as a dangerous place to be after dark.

That is outdated information. Downtown is fine after dark, especially if you're in Dan Gilbert's security zone. He's got cameras and security people all around his buildings 24 hours a day.

Now as I tell many others there are parts of the city I wouldn't visit in either the daytime or at night. But there are very few good reasons to ever visit those neighborhoods.
