Had a cool exchange with my neighbors today. They are like late-50s/early 60s and had asked us to watch their house and grab their mail for the weekend. Today, after returning their mail, I apologized for not getting it to them last night and they said that they had stopped at a relative's house on the way back to watch the show. And then, she told me that she had ordered all the books and was reading through them.
Not exactly the demographic I would suspect, but pretty cool.
