Why waste one of Detroit's rare sunny days inside a stuffy art gallery? The city boasts an increasingly incredible outdoor art supply, from an ever-evolving eyeball-grabbing mural district to public sculptures and more. Get a car, hit the road, and check out some of these outdoor works of art. (Many of these spots and plenty of others can be found in Art in Detroit Public Places by Dennis Alan Nawrocki, available from Wayne State University Press.)
