Chicago was horrible as well. The toll roads are the worst, they put so much salt down and then the trucks turn it into a mist that gets into the seams and inner panels and rusts these old cars badly. Thats why I turned to Krown, they spray inside the doors and rockers and seams with a oil that seeps between the metall to nuteralize the salt. Indiana dosent seem to be as salt happy and seems to use sand in some places, especially rural areas. We'll see, this is my first winter commuting in Indiana.
