Realistically it’s only those 1-2 days after snowing when things are still being cleared that it’s an issue. I bike commute 52 weeks a year in Minnesota and there were only 3 days this year I regretted biking. 2 snow days and one heavy cold rain. I can always supplement another option on those days.
I thought they die because they can no longer support their weight either because they can’t digest enough or hunt enough food to sustain their size?
