Earlier quoted context omitted.
He said he's lived in both SF and DC, if you had bothered to read past the first sentence you'd know this..
I certainly did read the whole thing, hoping to find some acknowledgement of MUNI. (He finally gets to it in the separate comments page.) He doesn't detail his living experience for SF, but for DC, it's one summer. As I noted, you can be a bay area resident for years and easily overlook SF MUNI, if you're not in the city proper and mostly ride BART.
In 14 years I've heard of "Muni" but never actually rode on of their train/buses - though, as you mentioned, I _see_ that "Muni" platform every single day when taking Bart.
