IT REALLY IRKS ME WHEN AFTER working all day, I sit down to watch the evening news only to find that the iconic anchor monster is vacationing. How about a little advance warning? Not that I have anything against Brian Williams, Forrest “Gump” Sawyer or the other fill-ins. It’s just that if this day was so inconsequential that it didn’t require the attention of Peter, Tom or that exotic two-headed beast, DanConnie, then why were the rest of us still required to be in harness? To the sacred slate of national holidays, let us add a few more happy observances like Brokaw’s Fishing Trip or Jennings’s Ski Jaunt.
