20 March is always "Sweater Day," honoring the birthday (in 1928) of Fred Rogers. "Mister Rogers" always wore a cardigan, with a tie, almost always on a white shirt. His ties were always muted but sometimes featured a small repeating figure like the horse-and-rider on mine. I hope you are enjoying "a beautiful day in the neighborhood" today.
