Now that you mention it, that reminds me of the two winters I spent in central Illinois. They didn’t have much snow removal equipment out there so they just laid on tons and tons of salt. It made a real mess because the snow would melt some, re-freeze into ice, thaw some again and so on. I was amazed to see cars two and three years old that were rusted out. I grew up in Vermont and while salt was used, snow removal equipment was plentiful and that was the first line of defense. Cars rusted out but not in two years.
