Plainfield averages 33 inches of snow, and road salt eats brake lines, exhaust and the underside of the car. Rinse the underbody through the winter and have the brake lines looked at whenever the car is up on a lift.

About 41 inches of rain fall in a year. Worn tires lose grip on wet roads well before they look bald, and streaky wipers are a cheap fix worth doing before the wet season, not during it.
