By the end of today's presentation for advertisers, Fox had filled the stage with a golden-robed choir and the cast of "Glee."

I'm just back from Chicago, where life is good. That is to say, where the Cubs beat the Cardinals in two straight come-from-behind wins. Sometimes -- even amid foul weather and more-foul economics -- it's easy to define "good."

I'll tell you more about Chicago soon. First, however, I had a chance to do some advance TV viewing; some notes:

1) It's hard to believe, but tonight (Monday, April 20) already brings the season's second-to-last new episodes of "Chuck" and "Heroes," at 8 and 9 p.m.on NBC.

We all know that Feb. 2 repeats itself over and over. That's what happened to Bill Murray in the "Groundhog Day" movie; the repeating was, we were told, a bad thing.

This week, however, I think it would be kind of good. Monday has way too many strong shows for one night; it would be a good day to repeat -- or at least to put our VCR's or TIVO's into hyperdrive.

I probably should have suspected this, but now I know for sure: This whole passenger-train thing really does work.

Movies and TV shows -- my main reference points in life -- always hint that trains work. They show passengers riding effortlessly; along the way, people find romance, sex and mysteries, plus a mean  guy who's intent on killing James Bond.

Still, I keep forgetting to try. My one previous train trip (from Minnesota to Michigan) had included fun and Scrabble; then I went back to my usual car life.
