Q: A desire to be closer to the urban scene has also attracted some young professionals to reside in inner ring suburbs such as Grosse Pointe and Royal Oak, Detroit. Detroit's proximity to Windsor, Ontario, provides for views and nightlife, along with Ontario's minimum drinking age of 19. A 2011 study by Walk Score recognized Detroit for its above average walkability among large U.S. cities. About two-thirds of suburban residents occasionally dine and attend cultural events or take in professional games in the city of Detroit.
