Building on that idea of bringing people of different backgrounds together, Thread, a local non-profit that supports academically underperforming high school students, organized dozens of dinners to be held on the same evening several weeks ago. In all, 1,000 people from different neighborhoods, races and walks of life sat down to eat at 100 locations all over the city. They got to know each other and reflect on our city's challenges and future. The suppers were a microcosm of our city's diverse population. Guests represented a rainbow of color and ethnicity: They were teens, college students, professionals, owners and employees of every type of business, community leaders and retirees.
