What is wrong with some of you?

I grew up in the CA bay area and always called them sunshowers. I didn't make that up: I called them sunshowers when I was a kid because the people around me called them sunshowers.

As an aside, I also taught linguistics at the university level for about 10 years. I do question the accuracy of many of Katz's charts because they very often do not match people's expectations, and beyond the level of "you expected this because you didn't know any better". I would take them with a grain of salt. That's not really a dig on Katz, either: difficult to study anything at this scale.
