My own contribution to this is: I live in the lower Midwest. We don't have blizzards here, very rarely does snow get more than an inch when it does fall, because the climate is too warm for blizzards. Our climate is too warm for full blizzards, but instead it causes ice storms consisting of freezing rain, which forms a casing of ice on anything it hits - the roads, trees, power lines, etc, and turns the roads into black ice, making any expedition dangerous. Cross-country skiing is not an option here. Nurses are expected to literally risk getting themselves killed on the roads or getting their cars totalled to get to work.
