At 6:45 PM tonight, Spring will arrive in Boston. There will be no robins in sight—let alone any orioles, cardinals or blue jays. In fact, it is projected to be snowing as the Vernal Equinox passes through New England. The snowiest Winter in history will mercifully come to an end—with, of course, more snow. Then again, Opening Day (April 6th in Philadelphia) is a mere 17 days away. And one week after that, the blow torches and chemicals should have cleared Fenway Park for play. As we write this, it is 26 degrees on this first day of Spring—and about to get a lot colder. No self-respecting robin would be within 1,500 miles of here.
