Last night’s episode of “Mad Men” gave viewers a much needed change of scenery — Don Draper and Pete Campbell flew out of Los Angeles to meet with various airline executives in pursuit of new business. But while Pete devoted his time to the task at hand, Draper took off for Palm Springs with a mysterious 21-year-old woman and band of pretentious, bohemian, and decidedly wealthy nomad friends. Don seemed to be incredibly intrigued by the laissez faire attitude of his latest conquest (yes, they did sleep together — so much for Don remaining faithful to his marriage) probably because she lives the kind of responsibility-free life that he kinda, sorta craves. It was fun to see the way L.A. was in the early ’60s, the bright sunshine of the poolside atmosphere a welcome change from the greyness of the Sterling Cooper offices. Also, Don Draper looks hot in sunglasses. Next week, it definitely seems like Don is going on a bit of a mission, taking time off from work to pursue something, or someone — there’s been a lot of questions surrounding what Don’s life was like as Dick Whitman. Might there be a love child out there?Other developments: Roger Sterling wants to marry Beta Secretary Jane — once his divorce from wife Mona goes through. And one of Sterling Cooper’s clients, a European guy who invites Peggy to a Bob Dylan concert, announced casually that he’s gay. Everyone freaked out, with the exception of Peggy of course.
