Ha Ha! I live in Ohio, just south of Akron, rust kills a lot of vehicles here, they salt the roads and also use a liquid brine, I think that's a lot worse. It all comes down to maintenance, people are too cheap or too lazy to wash the crap off of their cars. We see a handful of people every week at the shop asking about getting rockers and cab corners fixed on 5 or 6 year old trucks, we turn them away because we don't want to deal with it either, there are shops around here that specialize in just rust repair, they can have it.
My last 2 trucks I have went south to buy, it's easier to drive 10-12 hours away than deal with rot, I should take my own advice and go south for a fox body, but this car was basically free, and I like a challenge.
