Just heartache for our friends in Boston, where I lived for 20 years. The marathon was a community celebration and rite of spring. I’d ride my bike in from Cambridge to watch the race finale on Boylston Street. On Monday, Bostonians did what they always do in the face of disaster: They rushed in to help their fellow Bostonians. My friend, novelist William Martin, summed up their sentiments. Please take a moment to read his blog.
