Two different commenters found this for us: The New York Times has an extensive interview with Matt Weiner, behind-the-scenes at auditions and other production, and general article. It’s too amazing to pull out a quote.

Okay, here are the quotes that hint at season 2, but please, read the whole thing, because otherwise I’ll just quote the whole thing (Nothing is spoilery, because Weiner wouldn’t allow that, but I’ll put the quotes below the fold for those of you averting your eyes):

This season, African-Americans are moving beyond operating the elevators at Sterling Cooper, though to what extent remains unclear.

The author says it’s unclear because Weiner is secretive, which segues into:

Weiner is incredibly paranoid about plot details finding their way to the media. “How do you know that?” he snapped about even the most innocuous things I mentioned about the second season. He is used to the secrecy of “The Sopranos,” and every leak, large or small, is a wound. He’s not wrong, of course. Why ruin the suspense? The first season ended on Thanksgiving 1960, and the fact that I knew that the second season picks up on Valentine’s Day 1962 horrified him.

Our commenters are the smartest people in the world, because Dan already guessed that. Yay us!

Weiner reveals a little about Betty, and the article also confirms the horseback riding:

“Betty Draper is getting angry,” Weiner said of Don’s Stepford wife and the mother of his two children, played by January Jones. “She is an incredibly beautiful woman who married a man she barely knows because he looks good on paper. Her mother has just died, and she’s realized that when her beauty disappears she will cease to exist. She’s not enough for her husband, and she doesn’t want to accept it. She’s terrified of dealing with that problem because she cannot get divorced, she cannot be single, she cannot start over. She is somewhat puritanical.”

Finally, my guess that Patrick Fischler and his wife are neighbors was wrong. Fischler was hired to play “a comic à la Don Rickles who is used in a Sterling Cooper ad campaign”—the character also has a “Jewish wife, who doubles as his manager.”
