I’ve been trying to find wandering classmates as the 60th anniversary of our graduation from high school looms. Not all are enthusiastic about returning to our home town in Michigan for a reunion next August. Nor am I, truth be told.

A sunny, August day in Michigan is barely warm enough for me. I’m far from alone in holding that view, as anyone with a casual knowledge of inter-State migration knows.

Take my graduating class, for example. Of the 79 living graduates whose whereabouts are known, 45 are still in Michigan; 24 are in warmer States (Arizona, California, Florida, Georgia, Kentucky, Louisiana, Mississippi, Tennessee, and Texas — moi); and 10 (inexplicably) have opted for other States at about the same latitude. In sum: 30 percent have opted for warmer climes; only 13 percent have chosen to leave a cold State for another cold State.

It would be a good thing if the world were warming a tad, as it might be.
