I'm so happy to be back in Madison for a week. It's a wonderful place. (Nothing against Cambridge, of course.) I'm sort of surprised I haven't been back earlier.
An intriguing thing about Cambridge is that I think the way that I have developed my habits and haunts there has basically made it as Madison-like as possible. In other words, I've shrunk the Boston metropolitan area to where it is basically the walkable part of a college town. What this says about me and my ultimate geosocial preferences will be left as an exercise for the reader.
Not to say that back in Cambridge I don't enjoy taking Red Line to Green Line to various things in Boston proper, but doing so feels like an excursion to somewhere else, rather than really part of the place where I'm living.
