. . . attempts to gin up lesser pairings into an admirable viciousness -- St. Louis and Kansas City? the Cubs and White Sox? -- have always failed. There is obviously something different about Boston and New York. . . .

What is obviously different about the Boston-New York rivalry is that the writers who write about it all live in Boston or New York.

The Cardinals-Cubs rivalry is pretty darn good.

Furthermore, the Cubs and White Sox play in different leagues, so the rivalry can't be quite the same. But when I was growing up on the north side of the city of Chicago, the dividing lines were very clear: If you lived on the north side, you were a Cubs fan and hated the Sox; if you lived on the south side, you were a Sox fan and hated the Cubs. The hostility was real, and it was intense.

Dodgers/Giants isn't bad as a rivalry. Toronto and Detroit sort of developed one for a while until Detroit moved out of the AL east and they hardly see each other any more.

The Cardinals-Cubs rivalry is pretty darn good.

I loved the George Will story from Ken Burn's Baseball documentary (which I watch every February). He tells of how he grew up in western Ohio. His he had the choice of being a Cubs fan or a Cardnals fan. His friend picked the Cardinals and grew up happy and liberal. He picked the Cubs, and grew up miserable and conservative.

You ain't seen a sports rivalry until you've been to a hockey game between the Rangers and the Islanders. And now that the Devils have been one of the top teams in the NHL over the last ten years, the Devils-Rangers rivalry is a hot one, too.
