Samuel Clemens once quipped...

So, I live in a region which is laughably called the "temperate zone". The name must have been invented in Southern England. Anyways, what this means is that we get all sorts of horrible for our weather (or we like to think so... or it comforts our frailty to 'brag as though that were so) whereas people in more "extreme" places only get one or two sorts of horrible --- desert heats, or monsoon half the year, or glaciers... A friend has reminded me that this means we don't get those noxious toxic tropical insects: it's too complicated for them. I might counter that Monarch Butterflies spend more than half their lives as tropical insects, but they're so pretty it doesn't matter.

Anyways, all that is preface or context for
