I've been writing about the events of 1989, 20 years ago.
Events of 30 years ago, during the winter of 1979-80, were also significant. But they were less fun. The Iranian terrorists' unique interpretation of diplomatic immunity, and the Soviet invasion of Afghanistan, are less enjoyable to write about than the fall of Berlin Wall and related events.
So, exercising my prerogatives as a blogger (able to write whatever I want, subject to the libel laws), I'll instead describe what I (somewhat subjectively) consider to be the best hockey season ever. (Wait until February, at which time geopolitics will enter back into the story.)
30 years ago today, the Philadelphia Flyers played to a 3-3 tie (back when there were such things in the National Hockey League) in St. Louis against the Blues. That brought their season record to 13-1-2. Their unbeaten streak had extended to 14 games. How long can it continue, and how will it end? (Heavy foreshadowing intended, especially regarding the latter.)
