So I have spent the past 24 hours in the presence of people who were stranded by the snow in NW Indiana.
Couple of observatons:
Pay attention to the weather along your route: A significant number of people were stranded because they had NO IDEA that there was to be any significant weather action for the duration of their trip.
Have equipment adequate to the task: Bald tires in winter are a BAD IDEA. So are worn out wipers, failed defrost fans, non working lights, etc.
Wear or carry appropriate clothing for the weather you can reasonably expect. Shoes, coats hats,gloves, etc. Your expected trip may be from house to car to another house, but you may have to detour from your route, and end up walking in those same office shoes, that thin coat, and REALLY need that hat to keep your ears a part of your physique.
To keep yourself from being beaten by your fellow stranded travellers, be on your best behavior around those who, like you, are stressed and out of their normal environment.
Whining might get your ass beat.
