Here's Patriot's Day, one of my favorites of the year, so often a fine spring day when the bikes and scooters come out, along with the sun. The Red Sox play in the morning, and after they lost their lead in the ninth, they gathered themselves and had a walk-off win. A little past Fenway, the Boston Marathon -- grandfather of them all -- is running. It's a grand day in the Berkshires and in Boston. And then two bombs go off. Where are we going?
