Dorchester booming, mostly for the better

It’s boom time in Dorchester. That’s what Bill Forry of the Dorchester Reporter told Bruce Mohl and me when we sat down to talk with him about what’s going on in Boston’s largest neighborhood. Dorchester is Boston’s grand melting pot -- or at least its polyglot point of convergence. It is home to more than 120,000 people with roots that span the globe, who, these days, mostly get along well.
