I can recommend these fascinating books for those who want to dig deeper (from their armchairs):How To Live In Detroit Without Being A Jackass, by Aaron Foley (bonus if you can ID the cover design reference)Detroit: The Dream Is Now, by Michel Arnaud (these 2 books alone will show the delicate balance needed between Old and New)Unreal Estate Guide To Detroit, by Andrew Herscher (highlights the quirky underground creativity that permeates the city)
