Good call. Some analyses have said that Draper is a Jay Gatsby sort of character, and that the swimming pool incident is further evidence that the writers might have this in mind. I thought his "idealized Megan" hallucination was sad ... yet another indication of just how screwed up Don is ... I always sympathize with his women more than with him. Overall the series has done a good job of depicting 60's drug use. Roger's LSD experience was one of the most realistic I've ever seen depicted. No need for silly psychedelic visuals ... just showing how people react and think on that drug without a lot of judgmental or illustrative nonsense made it more meaningful than it might have been in lesser hands. Not sure super-uptight Pete smoking pot is necessarily a good thing, though. That guy is just about ready for a nervous breakdown. Nice references to the Chicago Dem convention violence too ... sort of comparing the sense of how the agency is in free-fall with how a lot of Americans felt about the nation at the time.
