Maybe Deziner was smart enough to wear appropriate clothing for the conditions when he was a teen?
And now he has a Concours, so that truly makes him a pretty smart guy.
I carry Sorrel snowmobile boots, insulated coveralls and a parka in the back seat of my commute car(s) all winter. And some tools. You just never know, and, yes, I've had to use them a couple of times. Once due to my own mechanical/fuel issue and other times to assist others. Even a relatively simple tire change situation turns into a dangerous condition when its sub-zero and windy.
Try to be prepared for the unexpected. There are lots of places up here where you could be on your own for too long not to be.
