Astronomical spring is five days away, and baseball season begins in less than two weeks, on Thursday, March 28, to be exact. If I correctly remember what I read, it is the earliest opening day ever, and, as last year, every team in both leagues will be scheduled to play. I don’t follow baseball as closely as I once did, but I am enough of an old fogey that the words “opening day” still get my attention. It is an undeniable moment of seasonal and attitudinal transition. Things just seem a tiny bit more normal when baseball is being played. Good thing, too. That’s about 75 percent of the year.
