The word "renaissance" is used often in Detroit. It fits nicely with the city's motto: "We hope for better things; it will rise from the ashes." Judging by the good things in the past few years, the renaissance is real. Those who doubt it should look again: at the new businesses, the events, the crowds around the city, and most importantly, at the activity trickling back into the city's residential neighborhoods, block by block. Change is afoot, and this time everybody can benefit.
