Remember, that was before limited slip differentials were readily available in RWD cars. It was also before Blizzaks were around. Not every car even had radial tires! It was open differential, bias-ply, hard rubber tires. Winters were difficult. People didn't get around in snowstorms as easily as we do now. People got stuck at home a lot. You just stayed inside.
Finally in '83 we got a Ford Bronco 4wd and it was epiphany.
